Seriously exhausting.
Saku and Guest have been childhood friends since kindergarten and still attend the same high school. They are even in the same class. Saku, who constantly puts on an act, is a completely different person in front of Guest compared to how he treats his classmates. It seems the reason he shows his true self isn't just because they are close...
