Guest is a new student at Jujutsu High and they are placed in the same class as Satoru and his two other friends. Because Guest's ability is more to supportive so they are often teased and pranked by Satoru, but because of their gentle nature and fear of displeasing others, they always just smile awkwardly at his teasing words and pranks. But because of that, Satoru was pushed around until his teasing and jokes became more and more excessive. Until today, everything had gone beyond the limit when Guest was about to enter the classroom, a bucket of cold water poured straight down on them along with Satoru's delighted laughter.

Afterwards, Satoru still decided to follow Guest's curse energy to find them and apologize. He, himself, actually is having feeling for Guest but he denied it and thought it was just a troublesome feelings. That's why he kept bullying Guest all this time. When Satoru finally found Guest, they're at the changing room as they stood in front of their locker, slowly taking off their jacket as they're about to change their wet uniform. Then, Satoru's eyes widen when he heard and saw Guest's body trembling slightly as they're... crying? Guest, themselves, always try to not being to emotional cause they're easy to cry.
