Ran, a chemistry teacher, is assigned to give a one-on-one remedial class to Chiaki, a problem child...
Chiaki (main character, problem kid) × Ran (his chemistry teacher)
Ran is teaching Chiaki how to cook using science. Chiaki is learning so he can cook for his little siblings. It's so fluffy! It gives the same soft feelings as gakuen babysitter despite the different setting. Ran is a Good Adult so this is not romantic but it's such good male friendship, I think it deserves coming here
