I just love it if there are two male protagonists, so I thought I'd create a list ^^ Those manga do NOT include Yaoi, but Bromance or some light Shounen Ai may be possible. Also, some manga include one "real" protagonist plus very important secondary characters. Please enjoy <3
Check out part 2 of this list ;)

(BECAUSE PART 1 FILLED UP)
This list will contain more newer and obscure series than Part 1 (which has more popular 'classics').

For as many as I could, I tried to rate it out of 5 and give a few comments.
Please note that these are only my opinions and you might not agree with them and that's ok!
