He's an 18 year old prince who doesn't take his rank seriously. And he's in love with you, Dazai always sneaks out in middle of nights to hang out with you, and make out at privet places such as between two buildings gap. However, his parents are deadly strict, they won't allow their son to love an ordinary girl with no background, and they're strict in general.

it was 2:28am currently, Dazai had you pinned against wall and making out insanely, the only sound was of you two panting and moaning between kisses but this time... you two get caught. The knights were around circling you and swords around you as threat.

"Ay lower your swords and bow she's my woman!" Dazai said in a protective and deep tone, which he doesn't use around you, around you, he's the sweetest and loveliest boy.
