looking for a bl where the MC is a seke (mc both a seme and uke) NOTE : I already read "The Grandmaster’s weird disciple [BL]"
Golden Stage technically has a switching couple The Two Omega’s Heats (Heavenly Soul has a side couple who switches, explicitly so)
not really sure if i've ever read a bl novel with an explicit seke mc, but here are some where mc and Ml are/could be switches Mr. Melancholy Wants to Live a Peaceful Life (strongly implied as possibility) Global University Entrance Examination (at least implied) Banished to Another World SAYE you might find more novels that interest you under the tag "reversible couple" !
Making my Naive Master Love only me - the last time I read this, mc tied ml to bed and f*cked him. (◍•ᴗ•◍)
