mc mentored by a sage!

last time my question was a little too long haha so i'll try to keep it short and sweet this time!

i'd really love some recs where the mc is under the guidance of a wiser (possibly older) sage, like a mentor x student or disciple relationship!!

i don't mind if it has romance either, but i would prefer to see more teachings/instruction than just pure romance if that makes sense :>

ALSO if anyone has any manga/hwa/hua recs with music or literature references, that would be great too :)

thank you in advance (づ￣ ³￣)づ
