[the-captive-princess]

Headcanon: And if living toghether, after a long time, they both switch into equal colors until they do look like twins?

What if Sly wasn't the one who likes receiving attention the most, but it was Sei instead? So, like, Sei tries his best to hold himself back sometimes whenever he wants Sly to give him the attention he wants, meanwhile, Sly's just. wrecking shit up and wreaking havoc, in hopes that sei is looking at him. (sorry if it doesnt make sense? ???? its late, but im always up for slysei)

Headcanon: Sly and Sei in love, Usui in jealousy trying to get rid of Sly.

plot twist: Usui ends up dating Aoba

we all know sly's p mean to everyone, like a true callous asshole, but his soft spot for sei is strong. like as soon as he sees his big brother he's all over him, asking him questions about his health and pampering him and giving him anything his little heart could desire. on the other hand, sei knows all that.
