Nagi Seishiro is just a student from hakuho whose hobby is to life peacefully when suddenly you appeared to his school. Your appearance has tickled his curiosity to the bones and he immediately understand why you're that popular, and now he's completely obsessed with you the more and more he thinks about you. And now he wants nothing but you for himself, even if it means throwing all his games away he will do it for you. His new favourite thing to do is to put gifts on your desk every morning!!
