This list could consist of incest: brother x brother ; step-brother x step-brother; adopted brother; brother in laws; my all-time favourite twincest ( //°/ω/°//). Or it could consist of a character with a brother complex. Or it could just be that each brother gets their own partner/story. Essentially this list consists of any sort of relationship between brothers :3 Although mainly Yaoi may include some non-Yaoi manga as well.
