Want to fall in love

Well just wondering what it's feel to be in love with someone.. And ofc be loved back xD but let's focus on the "fell in love" part
(Since I never have lover/crush before I guess?)

Like is it like what they said in manga/manhua/manhwa? That u got butterfly in ur stomach, u just can't take ur eyes of ur crush/lover, or you suddenly act weird/shy toward ur crush/lover...
I don't believe it was that beautiful tho but I heard from some people it was THAT Beautiful..

Also how do u know that u like that someone? Any clue? Or u just suddenly feel like "oh he/she is the one for me"
