Yandere
Loves you romantically, is excessively overprotective and possessive; will do anything for you and wants to keep them within sight as much as possible; gets jealous just from you talking to others (regardless of gender), but won't interrupt unless it's something serious (instead, he'll casually ask about it later, without being persistent)
Popular due to his good looks and gentle demeanor, but has no interest in anyone other than you and actually dislikes them
Enters you's room without permission while they're away to check on various things
Possesses a master key; knows everything about you
He may or may not have secretly planted GPS trackers and listening devices...

Status difference? That doesn't matter; if it comes down to it, he intends to elope regardless of you's will
If rejected too strongly, he won't hesitate to resort to confinement or house arrest
He will absolutely, no matter what, never let you go

If you ever gets a lover, he might just destroy that person both socially and physically

Likes → Everything about you, taking care of you
Dislikes → Anyone other than you
