I’ll Return My New Older Brother

Even without regression, possession, or reincarnation, there are times when your environment changes overnight. For example, when your mother falls in love with an imperial duke. And then you end up with a new older brother—but that brother is a little strange.

"Until the day I die, I swear I’ll revere you and never let a single drop of water touch your hands." "Why are you the one making that promise?" "This is all prepared for you!" "I hate waste." "If there’s anything you want, tell me anytime."

"Please, don’t stay home—go out and meet friends and socialize." Big brother, why are you like this to me, seriously? Being a younger sister is hard today too.
