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)
-Generally being a classy gentleman
Since it's Valentines day, you have better-than-average odds of scoring with her, or at least getting a second date. The point is, you don't want to act like you're trying to score with her.
ええとーー
OPの専門は彼女ありませんでした。
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,...
