Is someone who follows the storyline able to give me a rundown of the plot and why they br...

so basically dohu at first approached the seme bc he wanted inspiration for a script for a bl novel (?) i think. then their relationship developed but he never came clean about it then the seme found out about it just as they had become very vulnerable and "honest" in their conversations and such. so the seme lashed out and bailed and thats how last season finished

I can't guarantee my memory of the storyline, but roughly speaking, it went like this: Our main character writes BL stories as a hobby. When he meets the blond guy at university, he is quite fascinated by the attractive man and considers him the perfect model for the top in his new BL story. To get closer to the blond guy, he wants to befriend him, which the blond dude doesn't think is such a great idea at first. Gradually, however, the two grow closer, sleep together, and fall in love. There's a bit of back and forth between the two, but eventually they become a couple. Then, however, the blond guy finds out that our main character has been using him as a model for his BL, which our main character had kept secret from him, and he's pissed. They have a nasty fight and break up, and that's where we are now, after a four-year time jump, at the beginning of season 3. Something else happened with the blond dude's family, or rather his mother, in season 2 but that hasn't been particularly relevant to the plot so far. I hope this helps, it's the best I can do^^.
