Opale's manga / #two pairs(1)

There are 2 stories, the first about the clumsy actor with poor social skills (seme) and a young actor for who he is a hero. The second one, my favourite (chapter 4 and on) is about both of theirs managers. The clumsy actor manager is captured by the other manager, which in fact is the brother of the young actor, and quite the bully in bed too...
