MC lives in a golden cage by Ml. There could be smth with like kidnapping or not. Maybe smth like a Reborn as a good child novel. Or MC is a wealthy young master but ML or family Help’s him from side (hiden from him) maybe smth with world hoping Where ML finds MC ( doesnt have to be it there) Anything with smth like this in it
Don't know if this is the one you're looking for, but it pretty much sounds like: Villain, Please Go Easy on Me (Arc: Dancing Girl)
Not sure if you’re looking for literal scene of a novel with a “golden cage” but a few novels where MC is extremely pampered by the ML (I.e does everything for him like the MC in reborn of a good child), I’d recommend: Rebirth of the Wolfish Silkpants Bottom if you want a similar-ish thing but a slow burn, slice of life, shounen ai, then: Living Next To The Male God
gonna recommend some manhwas The Night Sun (밤의 해) completed 34 ch, smut, yandere ml, stockholm syndrome, open ending but i dunno if there any english tl, available in indonesia Tied to you / A link between relationships ongoing. literally my fav manipulative ml, he never force Mc but ‘lure’ him to make a decision that Ml wants. no yandere and healthy relationship. adapted from novel
