He actually have feelings for his junior, the seme or male lead (ml). He said he realized it late, and that the ml is the only person he doesn't want to know he's gay because he assumed ml was straight and would avoid him.
He also said he thinks he might have been gay for a long time but repressed it, suggesting that they (mc and ml) may have had mutual feelings for a while.
I totally agree with you, if only one of them had confessed earlier, mc wouldn't have to meet his cheater, blackmailing ex.
The second story got me frustrated. Why did the uke want to break up just because his junior knew he was gay? It's not like he had feelings for him. And I kinda felt what the junior felt, if only he had confessed earlier he could've been the uke's first instead of that cheating asshole.
