Minato and Shizuma from Therapy Game are one badass couple. Its a series with a prequel, so read them in order of 1-4! Jackass! and Blue Sky Complex are also great couples. I'm also obsessed with Melt at Night too.

My favorite webtoon couples:

https://www.mangago.zone/read-manga/bbanana_scandal/ Both couples are great, but I personally like the couple in season two for multiple reasons. But this is probably my second favorite

I would like a confident and badass yaoi couple manga...if its coloured then perfect and if not then also perfect
