Hey boy, focus on your O levels first.
Take care of your hormones later.
It will pass. Seriously, when you get into JC, you will forget this
really really fast.
BTW just curious, are you from a single sex school? If not why so
uptight?
You and her not really close even in primary school judging from
your account.
Of cos if you are really interested in her then just go all out
lar.
But still, concentrate on your O levels first hor.
Unless you are IP/DSA/thru-train student then I nothing to say.
