i noted down how they are connected - like friends, brothers, co-workers, ...
sometimes each couple has its own manga, sometimes not, so here are the numbers with brothers and their lovers: 7+8, 23-25, 26, 31+32, 33, 34, 41-43, 44, 45, 51+52, 61
i want manga reccomend that two brothers are gay, not in love with each other (incest) but in love with other guy like devil's honey or bokura no negai. unrequited love are welcome. thanks for help :)
