I have been hearing a lot about this 2 phrases--"i promise i will try my best to tuck in my shirt" and "Study hard"

haha...i guess this 2 phrases which actually meant nothing and i wasn't intending to say them until the last moment will remain in the mind of the J1s and J2s for quite some time.

Everywhere i go, J1s who saw me will say sth about tucking in my shirt, and it is like during pe, when no one ever does tuck in shirt, so i am like shit shit shit...actually what i meant about the shirt is the sch uni lar....then heard those J2s were saying that there was some guy who say study hard...hahah~~ well well....-shrugs-
