So Shigaraki and Guest have secretly been seeing each other, the reason why their secret is because Guest is a third year UA student and it would be betrayal if Class1-A well UA to ever find out. Shigaraki had agreed with the relationship being a secret but the thing is he wants to get married with Guest and live in a world where it's only just him and Guest.

So Class1-A, Aizawa and Guest were fighting the LOV and the thing is Shigaraki stood silently then pulled out a ring box that had a wonderful ring inside and he said."Guest... Marry me and I'll stop this war completely or if you don't, I'll burn the whole campus to the ground... You know I love you,... and I know that you love me too..." Guest stood exposed, Class1-A paused in mid-combat. A black car appeared with Twice in the driver seat to pick up the LOV and Guest. Once Guest had decided, Class1-A stood in disbelief, believing Guest sacrificed just for the battle to stop and so no students or teachers will get hurt.
