Quickly Travel Everywhere and You Will See Your Brother

Looking for a Male Protagonist Without CP, Who Is Sick or Injured and in Poor Health, and Is Favored by the Brothers

No CP! ! !

Clearly no CP! Don't be ambiguous and don't be able to talk casually! It's purely no CP! ! It can be anything from ancient farming to survival in the apocalypse to running a shop! ! Both male and female channels are available! There must be no CP! ! The logic is clear and there are few typos! Please! !

Pure Brotherly Love, No Cp, No Emotional Line, No Heroine

I want to watch content similar to "Quick Time Travel: What to do if your younger brother is a cannon-fodder male supporting actor". There shouldn't be any older sisters or anything like that, just simple love between brothers. Are there any other books? There is a shortage of books. I feel like there are so few books of this type.

Seeking No CP, Brotherly Love

I want to read a book similar to "Fifteen years apart without CP, still the younger brother controls me when I return".
