Guys recommended me BL story where the top gives a vibe like" I'M YOURS instead of you are...

Turning

ghost nocturne if you want him to actually say it out loud.

if u just want that vibe, then missing love but i warn u this is full blown angst
honorable mentions would be sahan, guiding hazard, happy together and red string quests

Thanks

I'm waiting for S3 (=・ω・=)
