If you don't know what is a 'dere', google it. :)

Lol no, I'll help you. A dere is a specific type of personality of an anime character.

Tsundere- Sehun and Xiumin
Cold and bitter on the outside, but secretly love struck by you.

Yandere- D.O and Chanyeol
Friendly and innocent on the outside, but is secretly a possessive and creepy stalker/killer.

Dandere- Lay and Kai
Quiet, shy and harmless. Always buried in books, but secretly wants to talk to you and be friends.

Oujidere- Suho and Kris
Charming, royal personality. Thinks they are a prince, even if they're not.

Himedere- Luhan and Tao
They think they are the princess of this millennium. They're usually identified by the 'ohoho' kind of laugh. (refer to media)

Kamidere- Baekhyun and Chen
They think they're god. No comment.
