But to summarise:
1. Kaido started accepting acting/modelling jobs because there were less suit action jobs available. He’s doing a project with his acting coworker Matsubara, who secretly doesn’t like Kaido since he wasn’t serious about the job/didn’t appear to be into it.

2. As part of the project, the client wanted to film Kaido and Matsubara’s daily lives for a week and then at their actual homes on the last day, which Kaido obviously refused. His manager (Ito), Matsubara, and his senpais had problems with Kaido complaining about his job offers.

3. Kaido’s senpais pulled a prank on him where they had the photographer take a photo of Kaido and Honda together. It is unclear what they said, but Ito and the photographer thought that Kaido knew about the plan. By the way, the senpais told the magazine that Kaido was gay, but the article just said they were friends.

4. Kaido started getting bullied at work for being gay, and his senpais “accidentally” pushed Kaido off a high place, causing injuries. Matsubara was the first to run to his rescue. Honda broke up with Kaido since he thought he was the reason Kaido was unhappy (after seeing the photo and his injuries).

5. Matsubara told Kaido to stop arguing with his senpais since it affected him and the other employees. He didn’t know the photo was a prank until later, and apologised for it. He saved Kaido after he fainted, then visited his (and Honda’s) apartment, explained his side, and the two became friends.

6. By the way, Matsubara used to be a student at Honda’s university where he had a crush on Honda’s friend Mikawa. His classmates found out Matsubara was gay right before he dropped out to become an actor. Because he sacrificed his personal feelings to become an actor, he was jealous of Kaido and took it out on him.

7. Matsubara explained the prank to the other employees, and everyone felt bad and apologised to Kaido. Ito didn’t realise the severity of the situation until Kaido fainted, dug deeper into the photograph incident and realised that it was done without his permission. The magazine issued an apology, and the senpais got their punishment.

The uke thought he was being bullied for years. The seme genuinely thought they were close childhood friends. Still the seme acknowledged that he was the reason the uke hid his hobbies and apologised for it (since he read out loud the manga the uke was holding). He also apologised for teasing him in the past, as he didn’t know how to express that he liked the uke.

The point is that although the seme teased the uke in the past, it was only during preschool/elementary. And while that’s still bad, it’s also very normal kid behaviour. In middle school, he realised his actions were hurting the uke, but as he had already unintentionally bullied the uke for years, they developed a misunderstanding. For example, when the seme was relying on his childhood friend by borrowing his textbook, the uke thought he was being forced/threatened. So while the seme was following the uke around trying to get closer to him, the uke thought he was being tormented, only to realise that the seme had never actually made fun of his hobbies.
