I'm looking for a manga with a character who...well x3
a sweet-smile guy whose real face is evil, or the reverse
I think the term is tsundere or yandere ( ? )

P.-S.
Girl with that kind of personnality creeps me out, exception for SkipBeat's Kyoko x)
AND
Forgive my english 🤢

Oh and thanks for your help ^-^

That's more like...Dereyan(?) o.O
A bit like Ami from Toradora :\
