I've only read duke's private tutor so recs are based on that
Same vibe: Cherry Blossoms After Winter Shame♡Application My Darling Signed in
Histroical but read at your own risk cuz some are pretty angsty/problematic: Who's Your Daddy? Shadow Crown Liebling! King's Maker Painter of the Night
Kindly recommend BLs like will the roasted beans sprout, Duke's private tutor, don't mix business with pleasure etc
