Chased by Mr. Billionaire

18 years ago...     "I don't know why'd you have to leave. You've been in our family all of your life. You're not just an employee to us Greg, you're my brother and bestfriend." Don Alejandro Lincoln, asks his family driver, his bestfriend ever since they we're kids, named Greg.     Greg's parents was also an employee to Lincoln family when they're still alive. So Greg, literally grew up in their farm together with Don Alejandro. But they treated him as part of the family. Alejandro and Greg became bestfriends until they grew old and had their own family. But Greg is planning to leave now.     "I have to. My wife just gave birth and I'm planning to take over my aunt's house in the city 'cause she's sick now. She has no one." Greg answered. This decision is also difficult for him. He's been living with Don Alejandro all of his life. They dressed him and sheltered his family.     "Lucas and I, there'll be just the two of us now." Don Alejandro  refers to his 12-years old  son, his mom died after she gave birth that's why Greg's wife, Lila became his mother figure.      Lately, Lucas is kind of obsessed carrying Greg's 2-months old daughter Ava. Lila and Greg lets him, they know how lonely Lucas is, being the only child.     The two men just stares at Lucas, carrying Ava again. Then an idea comes into Alejandro's mind.     "I have a proposal to make."     " What is it?"     "You know, we're both getting old. When Ava turns eighteen, I want her and Lucas to get married. I just want him to be with your family. This was the only time I've seen him so happy."      "I don't know if that's possible. You know, when they grew up they'll have their own minds. It's not that I don't want to. But we can't tell."     Don Alejandro turns to Lucas. "Hey Lucas! How'd you find Ava? Is she pretty?" he asked.     "Yes Papa! I'm sure she'll be prettier when she grew up." Lucas answered back, smiling.      "Do you think, you can marry a girl like her in the future?"     "Oh... we're both too young for that Papa. But that's not impossible. If I  can marry her, then why not?"     "I see... Let's send them on the gate. They're leaving now."     "Okay Papa," but before leaving, Lucas whispered something in little Ava's ears. "Don't get any boyfriend when you grow up, I'll come find you and we'll get married."
