Kaguya's advice is for herself and Mokou more than anything.
You see, love is not simply letting your partner hear just praises.Sometimes it's important to act cold towards them.I can't... go back...What's wrong? You're looking kinda pretentious today. It makes you look stupid, you know?If you're gonna say things like that then I won't play with Chen anymore!Want to know something good, Inaba?Th-that's it!H-hmph!Sit!Woof!It's also important to kill each other.Eh... Teh-chan...Y-yes...I don't know what you were thinking but... it's useless to fight against your true nature, Teh-chan.Not with this body that already can't resist Chen...
