The mc had just walked out on the seme at the restaurant, having just rejected the seme's proposal that they get together just because they're "compatible" and not because they love each other (he basically told the seme he didn't want to be with someone who didn't love him, and the dumb seme didn't take the hint as his cue to confess that he did love him).
So, the mc saw that random couple having their marriage proposal in public, with the guy telling the girl that he wanted to marry her because he loved her, etc etc, and felt horrible. The cherry on top was that it was this exact moment that was chosen by his boss and the seme's brown haired friend (who have recently teamed up to secretly help the mc get over his "unrequited" love for the seme) to send the mc that recording that the seme's brown haired friend secretly took before, of the seme admiting to him that he "didn't love" the mc as anything more than a friend... Then the boss and the seme's brown haired friend discussed whether they had done the right thing by having the mc listen to that recording, and how they're both still kinda interested in having the mc for themselves.
so basically they were eating a restaurant and the guy confessed but those other guys had sent the recording of the guy confessing saying that he doesn't like him in that way. The green hair guy then concluded that the confession was fake and when he went to the bench he basically listened to it the recording again
idk if that helped
The scene in the bench was after the Uke and the seme had dinner. The two guys His send him an audio recording where in they ask the seme if he loves the uke..The seme still denying his feelings, he said he just treat him as a bestfriend. After hearing the audio, the uke get hurt. That audio recording was take when the two guys cornered the seme in the bar. The two guys wanted to help the uke to move on and let go his feelings towards their prideful and stupid seme.

Can someone explain this recent chapter to me? I’m a bit confused especially the beginning and when the guy was on the bench looking at his phone
