Do yoy remember your first otome CD/game/visual novel?

[ramenfor2]

I was trying to remember this morning what was my first Otome CD drama I heard and I think, if I'm not wrong, that it was a yandere brother sneaking into his older sister bed at night (in DLsite because of an ad on twitter hahaah). It freaked me out but honestly, here I'm, looking for more hahahah.
