So chapters 1-4 are all just chapter 1 split up. There are 15 chapters out in the raws right now. I would also like to clarify some of the spoilers on previous comments. If you read them, it doesn’t happen until chapter 8. If you want some additional spoilers, I’ll post some below.
Now then…
The clarification:
The uke does cheat on the seme via blowjob with a black-haired man (Yakura), plain and simple. However, there’s a reason for it: the uke has a very twisted past with Yakura. TRIGGER WARNING: it involves grooming/sexual predation. Do not read the next bit of text if you will be triggered by it. With that out of the way….
The uke was a child when Yakura became his tutor (a teenager/young adult at the time). The way Yakura was touching and interacting with the uke was inappropriate, but never escalated to sexual acts until after both were adults (as far as I can tell with what’s shown)
If you want further spoilers:
When the seme saw the uke giving Yakura a blowjob, he broke up with the uke. Later on, due to something happening between the uke and Yakura, the uke ended up mentally broken. The seme goes and helps the mentally broken uke. My guess is that the uke annd seme end up together in the end.
