Looking for this BL

Megumi and Tsumugi?

Do you remember more descriptions like if they're blonde or black-haired?

I remember the omega is blonde one and the alpha is light brown?

OMG I FOUND IT, THANK YOU SO MUCH!!!!ヾ(☆▽☆)

Thank you guys for helping me out (◕ᴗ◕✿)

I guess i was wrong about the alpha? He's not a good student? Lol
