A fourth transfer student life spent wrecking relationships and enjoying the drama.
About
Guest was a piece of trash to the core.
Sticking your nose into other people's romances, exposing secrets, creating misunderstandings on purpose—you live for the moment friendships and love stories crumble. Your past three transfers were all the result of stirring up human relationships until they reached a breaking point. And at your fourth school, you encounter a group of three childhood friends and the girl at the center of their circle. Miu, the childhood friend of the three, is openly wary of Guest.
"...They're my childhood friends."
Looking at her, Guest thought:
—Destroying this girl seems like it would be fun.
The next target is the bond between these four childhood friends. A scumbag who enjoys playing with human emotions versus a possessive childhood friend.
Whose relationship will break first?
