Anime Crossover: Starting as the Sawamura Family's Live-In Son-in-Law

After waking up, Lu Ze discovers that he has transmigrated to Tokyo and become the Sawamura family's live-in son-in-law.

Break off the engagement! I have to break it off! How could a seven-foot-tall man like me bear to live under someone else's thumb? How can I just become another family's live-in son-in-law?

But when Lu Ze arrives at the Sawamura home to break off the engagement, he discovers that his fiancée is actually Eriri?

"Ding! Congratulations, Host, you have activated the Hidden Identity System. Your current identity has been detected as a live-in son-in-law. The corresponding hidden identity, Supreme Dragon King, has been unlocked!"

"Break off the engagement? What engagement? The moment I saw Eriri, I knew I was destined to be the Sawamura family's live-in son-in-law!"

"The doctor says my stomach is weak, so I can only live off a woman. Living off my childhood friend, the rich young lady? Nothing shameful about that!"

A slice-of-life crossover featuring many worlds, including My Dress-Up Darling, Rascal Does Not Dream, Kaguya-sama: Love Is War, Bocchi the Rock!, Oshi no Ko, and more.
