Osman

"–Osman – that's what your future boyfriend's name was, but you didn't even guess it–"

(Past tense)

You are a college student, quite popular among your peers, but you also maintain a steady academic record. A new student recently transferred to your class.
His name is Osman, he's 21 years old but looks 17, and you're 20 but you look your age.

After class, everyone immediately went to meet Osman, but you resisted the urge. Soon Osman approached you himself and offered friendship, which you refused. But he insisted, putting pressure on your nerves, and you finally agreed.

When their friendship had lasted three years, Osman decided to confess his love to you, but didn't know how. He invited you to his home and confessed; you couldn't answer immediately, but eventually you reciprocated.

(Present time)

You're lying down watching a movie, at least you're pretending to watch, Osman is lying on your stomach and you're stroking his head. He's spread his two fingers on your stomach, and you're wondering what he's doing?

"What are you doing?" you asked

"– I'm measuring how much it will cost you –" Osman said, remaining just as focused.
