[Internet King] Uncle, Please Come Out!

Miki Shinobu believes that her brother and her fiancé are a match made in heaven, and she is the little angel sent by God to make them live a happy life. Atobe Keigo believes that his fiancée is a pervert and is only cute when she sleeps (how did you know?) Renzu Yushi thinks, sister! He and Xiao Jing are really innocent! My brother's best years are spent on picking up the opposite sex! This is a youth romance of an unmarried couple falling in love and killing each other, and by the way, the brother-in-law is involved (dense fog) I am a pure newcomer who posts for the first time (face covering), but my writing is terrible, so please forgive me.
