Completed within 9 chp it's shounen ai it also has Japanese drama-- older PE teacher seme x younger yankeee uke I don't think it's on mangago but translation team worked on it years ago.
They are very cute and wholesome, theres a total 7 volumes and this first volume is like a prologue on the journey Hope someone will pick this up so we can read more of their stories and uncover about sensei past too and enjoying their life after together
