No problem, I will try to explain:
Momo is a kagema, a male prostitute, he works at the brothel that manji was, Manji doesn't like brothels but he has to go there to visit him, he had to buy a room with a prostitute since you're not allowed to stay there alone, but since he's gay he was only waiting for Momo to finish his work so they could go home together. Momo, for some reason, didn't had any customers that night so he was playing with make up and kimonos (many kagemas were also kabuki actors for feminine roles so they were allowed to wear makeup), Anii was sleeping but he hears Momo and his friends and gets out of the room and kiss Momo, the alarm rings telling everyone that working hours are finish, both of them go home by the end, that my opinion but I can't say that is 100% (=・ω・=)
I think that's because the story mixes past and present sometimes? I don't see many other reasons for them to be in the brothel and what the lady said leads me to believe that Momo was working. If that's not it, then they were just playing there, but Ani says how he doesn't like brothels and also Momo said how he "didn't had any fun" but well, need to ask the author to know for sure
Its alright, the story is hard to understand tbh, a lot of people in the comments are saying thar is quite confusing as well, english is also not my native language so don't worry about apologising! I make mistakes all the time, brought and bought is one of the most frequents for me actually ٩(๑❛ᴗ❛๑)۶ glad that I could help
I don't understand the content in chapter 2. Look like the seme goes to the brothel and leave Momo out alone? I am not good at english so can someone explain the content to me, please!
