So I have a crush, he looks like a younger Song Joongki, we are classmate so we are kinda close. But I think that he likes me, one day he liked all of my instagram posts, and he always greets me. Every time we talk we always making eye contact. But I'm not 100℅ sure the he likes me. What do you think? Anyway, I want to be closer with him, so I hope you'll give me some advice, thank you!
