Spoiler!
They will break up and the seme easily accepts their break up without forcing the uke. He will quit that club together with his female clubmate. He was exhausted and didn't want to see the seme. The seme will be saddened because he will never see the uke since it quits their club. The side couple is gradually progressing. They will have one-on-one conversation relating to seme's friend's past profession being a musician.
