I had my first crush when I was 5. I don't think anyone had noticed me at that point. So yeah...it was me on someone else. He was a boy 10 years my senior.
One in 5th grade I think, I totally had a crush on this guy XD. But I also had (2 people in 5th grade who were in the same class as me) Have a crush on me and I was like OMFG no way! Then they ended up telling me they liked me and it was kinda awkward after that because the 2 boys that liked me were also 프렌즈 of mine XD.
My first one was me crushing on someone else... though, I never had a serious crush on someone. Now, years later.. it seems like 더 많이 people are crushing on me while I'm crushing on no one. ._.
