he's onlyin one of my classes and sometimes he even purposely leaves class at the same time as i do and once he came up next to me while i was walking with a friend and he just kept the same walking pace as i did next to me,saying nothing(it was cute but a bit awkward).also,once while i got up and was passing the group table he sat in class,he smiled and i smiled back and a girl in his table(when i turned around) said "awww,he smiled and she smiled baaaaack" and he looked down.anyway,he's two years older than i am but he looks like a really nice guy and people say that we'd look very cute together.
it'svery frustrating cause i'm sensing he's too shy to talk but,i personally don't want to randomly go up to him and say hey because it's been going on for 4 months like this.what should i do?
