I think it will be difficult right now because I have to study a lot, and I think I'll need to study for 5-6 hours a day even after I'm thinking about surgery, but I heard it's not good to keep my head down... ㅠㅠ By any chance, how long after surgery will it be okay to study? Should I do this while keeping my head down as much as possible..? Hahaha Qㅠ
