the story of the side character on the isekai world

hello everyone my name is William Robertson I am the main character of this story. today I will how I met fl and how my love story goes I guess? so anyway I will tell you how my life on as a side character on another world this how it goes long ago There's a boy who got lost in the palace, but he found a beautiful garden in the palace there's as full of flowers and a hill and on top of the hill, a tree, and a girl under the tree, her was yellow and her eyes was blue and her skin was pale white. That girl crouched while crying he approached the girl slowly and ask. "Hey, why are you crying?" the girl lift her head around she replied "Because they said I'm useless." William wondered why they said that so he ask "Why they said that you're useless?" "Because they said that I couldn't do what a proper princess does." "Why they said that you couldn't do what a proper princess does?" "Because I always mess up." "Why you always mess up." William ask full of question The girl got angry because William repeatedly asked questions." "You're so annoying!! Why are you asking why, why, why! Don't you have any new words to say!? Sniff, sniff." "Now, don't be angry. It's bad for a girl to get angry." William wondered why the girl is angry when he just asking some question "Whose fault it is that I got angry, or are you here to make fun of me because I'm..I'm useless!" The girl started to cry again. The boy started to panic, the boy said in his mind. ('What should I do if it like this then this might gonna work") "Now, now did you know if you always cry. You will become ugly." The girl stopped crying and then suddenly cried much more than before. As the girl started to cry more, the boy panicked in his mind. ("What should I do? She is crying much more than before?") And then he remembered what his parents said. "If you see someone crying, then make them laugh, okay." "Okay, father! If I see someone crying, I will make them happy, father!' The boy said with a cheerful smile and then after he remembered he smiled gently he called the girl while making a funny face the girl look at the boy after he sees the face of the boy she laughed so hard and she said "Hahaha hahaha! What's with that face? Could you stop it your making my stomach so much from laughing." "I will not until you promise that you will not cry anymore." "Okay, fine, I will stop crying could just stop that strange face you making me laugh so hard that I will die, hahaha!" " Okay then, if you cry again, then I will make a funny face again to stop you from crying again." He said it with a positive face, and the girl was flustered. "What are you trying to do? Are you flirt with me? Do you know that I'm a princess? You know that!" "What are you saying? I will never do that; I'm just a mere noble compared to you." "It's okay if you know how great I am." The girl says it with a proud face and the face of the boy like what the heck. "Um, could I sit beside you because I'm tired of standing here." "Okay, bye, the way, what's your name?" The boy sit's beside her. "My name?" "Yeah" " My name is William Robertson, and you, what's your name?" "I am Alexandra Hartman" "Oh, so you're the birthday girl, then why are you crying here when it's your birthday today?" "I got bullied today, and they said I'm a failure, useless, and just good for nothing, princess." Alexandra said it like she gonna cry. "Hey, dint I tell you not to cry, and who cares if they said that you are a failure, useless, and a good for nothing? They just don't know how great you are" William said it with a serious face. "Your right. They just don't know how great I am." Alexandra said it with a smug, but suddenly, her expression change. "Hey, why are you so down?" "because when I think about our conversation I don know where I'm good at" "it's okay if you cant where you are good at just find what you like to do" at that moment William looks cool "what I like to do?" "yeah what you like to do" "what I like to do but I don't even know what I like to do or what I can do," Alexandra said with a gloomy aura. "hahaha cheer up you will find it someday where you are good at" Alexandra approach William and her face was so close to mc face and her eye is glittering and she said "Really!?" "yeah" William turns his head on the right and he said to his mind (" ah she too pure I feel like I'm a bad guy and she too close as a princess shouldn't she do what a princess do ahh I forgot she can't do what a proper princess do. no no even she can't do what a proper princess do as a woman can she distance a little bit?" "Hey, William?" "what is it?" "Why are you turning your face to the right?" "Because....because you're too close!!! Alexandra's face turn red and she immediately distances herself then suddenly there's somebody calling William around the corridor at the palace "William!!! where are you, William!!!" "ah I have to go now my mother is calling me" William stand up then suddenly Alexandra grab William clothes and she said "um well, will you come here me if you have time?" William look at Alexandra's eyes tell as pls come here I'm so lonely I don't have any other people to interact with other than my parents William smile and said "yeah because we're friends right!?" Alexandra was super happy that she jumped on William. William stumbled and then Alexandra said "Yeah, we are friends!" Alexandra said it with a big smile meanwhile mc mom was trying to find William and then she saw what happened and she say " Ara ara younger this day are so bold now" William heard what his mom say and then he immediately gets up and runs to his mother then he said "mom it's not what you thinking" Alexandra got disheartened by what William said so she approaches them and she asks again "um...will you really come here again, William~?" Alexandra was scared or anxious because maybe he will deny it because his mother was here because maybe he will get embarrassed that she is his friend. when William turn around and see Alexandra he sees or feel that Alexandra doesn't trust him Willliam feels angry to the point that he scratches his head and then he approaches slowly Alexandra and then grab her shoulder tightly and then he said this to Alexandra loud and clear "hey listen no matter what you think about something bad from me to completely distrust me. I will tell you don't lump me with some other people! who breaks their promise to someone I am different from them why I am different? it's simple, because! I! am! a man! of principle! I! am! a man! who won't break a promise! unless they break their promise from me! so your the one who should watch out because maybe you will the one who will break the promise." Alexandra got pissed off at what William said because he said she will the one will break the promise William said and then she shoves William's hand on her shoulder then she approaches William closely and then William steps back slowly because she is too close then she points his finger at his forehead while she talks "ha!~ me will break a promise? no way! and you wouldn't even how I feel! when someone always!~always!~ makes a promise but they always! break it~!" Alexandra started crying and William mumble something "tsk annoying always crying what a crybaby" "William mother heard what William said she pinch his ears "ah~ah why are you pinching my ears mom?" "you said annoying to that poor little girl don't you?" William was flustered "hahaha what the hell are you talking mom I dint say annoying maybe it's just your imagination William said while scratching his head and then his mother said "any way you should make her stop crying that girl is too pitiful" William look at Alexandra and then he "sigh~hey hey can you stop crying or I will break our promise" Alexandra cried strongly "tsk~here" William give Alexandra a necklace and her mother was shocked and Alexandra stop crying and she looks at William and she received what William gave and Alexandra ask "what's this?
