Animal characteristic (Fox)
Double personality
Popular guy x shy timid guy
No drama
Teacher x student
School nurse (rival)
Younger seme x older uke
This is the sequel of the main story https://www.mangago.me/read-manga/sensei_wa_sonna_koto_oshietenai/, however the first story is not my favourite. The school nurse has his own story too, you can read the spin-off
Omegaverse
Alpha x omega
Master and servant
Heart wrench
Confinement
Supernatural/ magic?
Rival to lover
Sacrifice
The story is overall very weird and rushed. It's beautiful but could've been better with more explanation
based on true story
personally, i like the story of the second couple more
teacher x teacher
Past lives
Reincarnation
Reunion
Highschool
Senpai x Kouhai
False bad rumours
Family issue
Slice of life
Sequel to Kimi to Parade
I'd say better prepared your heart and tissue. Also the extra last chap....ill leave to you to read or not
