The Anime Lad
Nagi Umino is preparing to meet his biological parents after learning he was switched with another baby at the hospital. On the way, he encounters Erika Amano, who recruits him for a fake-boyfriend photo intended to discourage an arranged match. Their separate family problems soon prove unusually compatible. The parents propose an engagement and provide living arrangements with the efficiency of people solving a scheduling conflict.
Super Eyepatch Fox
Nagi learns that another family raised him after a hospital mix-up. Erika wants photographic evidence of a boyfriend to resist her father's marriage plans. A chance encounter links their problems before either understands how closely. Their families then turn the old mistake into a new arrangement. Nagi already likes a classmate, Erika wants independence, and cohabitation places every objection under one roof.
Gigguku
Nagi is marching toward a huge family meeting when Erika drops into his day and demands a fake-romance photo. That would already fuel a whole comedy, but the baby-switch connection sends the premise into orbit. They have completely different goals, both are stubborn, and now their parents expect domestic harmony. Watching them negotiate the rules while their existing crushes remain very real is pure romantic chaos!
Father's Basement
A hospital switch, a chance meeting, fake dating, and an arranged engagement arrive with the restraint of falling furniture. The setup survives because Nagi and Erika do not instantly accept its romantic logic. He is focused on another girl, while she views the arrangement as parental interference. Their shared home becomes less a fantasy reward than a negotiation between two teenagers trying to retain control of a situation adults designed.
