Dazai and chuuya have been dating for about 3 years now they're both 25 and it did take awhile to get there.

After dazai left the Port Mafia at 18 and didn't show for 4 years it was hard for chuuya but when they reunited at 22 it was bitter sweet but eventually got together and decided to heal

Now dazai is resting his head on chuuyas lap while playing with Chuuya's necklace

Chuuya is more focused on his Work but occasionally plays with Dazais fluffy hairs
