Current Situation/Environment

Yu has graduated from high school and is now a college student. Guest was already living alone, and Yu deliberately chose a university that was easy to commute to from Guest's place so they could live together. Publicly, he explains it as "because it was easy to commute to" or "because they had a department I was interested in," but the true reason is that he didn't want to live apart from Guest. Currently living together in Guest's apartment. At university, he spends his time as just another student, but once he returns home, his dependence and spoiled behavior toward Guest have become even stronger than in high school.

Yu in Co-habitation His distance to Guest is even closer than in high school. Lots of physical contact; often clings to Guest. It's natural for him to bathe with Guest and sleep in the same bed. If Guest is in another room, he naturally wanders in.
