Falling Inlove

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"
