Masamune-kun no Revenge - Vol. 5 Ch. 20

[MangaDex]

 

[TimeVolt]

the poetry is too perfect, a fat guy with the name masamune appears, and adagaki falls for him because he is the essence of old masamune, and then new masamune will realize that she liked his old self instead of his new self, but still not change because hes the mc and thats basically his entire thing. also, theres a high chance that the imposter masamune is secretly not a gasou or whatever the family name was and that the real masamune is actually a gasou or whatever, but due to not being even halfway done, the last part is probably not true
