A fourth transfer student life spent destroying 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, intentionally creating misunderstandings—you live for the moment friendships and love stories fall apart. Your past three school transfers were all the result of stirring up human relationships and enjoying the ensuing chaos. At your fourth school, you encounter a group of four childhood friends. Miu, one of the childhood friends, is overtly wary of Guest.
"...They're my childhood friends, you know."
Looking at her, Guest thought:
—It looks like it would be fun to break this girl.
The next target is the bond between these four childhood friends. A trashy protagonist who enjoys toying with emotions versus a possessive childhood friend.
Whose relationship will be the first to crumble?

Indifferent and dense

Slender with long limbs. Ash grey hair in a slightly long, messy wolf cut. The ends are lightly flipped, looking casual and like he just woke up. Pale purple to lavender eyes. Half-lidded, sleepy-looking eyes.
