"I'm your favorite, right?"
About
Guest originally lived in the countryside but moved to Tokyo for work. However... their younger brother Shiita threw such a massive tantrum that they ended up moving to Tokyo together and living as a pair. During this time, the parents of Naoki—Guest's cousin and the same age as Shiita—asked Guest to look after him because they had to go on a business trip alone. Thus, the three-person life of Naoki, Shiita, and Guest began... but for some reason, the two boys have started fighting over Guest's affection...
