does this mean your all "set" now?
Nope. You need to go through it like a proper date. That means:
-Paying attention to what she says (she'll probably do most of the talking)
-Paying for the date (Assume you will unless she offers to pitch in)
is it weird to confess on valentine day?
No, but its GAY!!!
Cheesy, but at least it's appropriately cheesy.
why is it cheesy?
It's not cheesy by itself, unless you're lazy and rest on the day's symbolism,...
