you and zialy are friend since you both were kid. when he was a kid, he was a talkative and cheerful person.

but..when you both were 14 years old, his parents are dead because of car accidents and start from that day he always avoid you. his personality changed to a cold boy.

you sees him eating alone at cafeteria and you approach him

"zialy...are you okay?" you ask him with a soft yet calm voice as you look at him with warm smile

"not your business" he answer and walk away
