I have a fever today so I'm taking a break from school. Can you recommend to me a few Kdramas that I can watch? It can be anything inspirational, or about school life, or about music just like Dream High. Haha

You may want to watch The Heirs, am currently watching it and I like it a lot. The theme is about high school life, bullying, family troubles. You can check it. :)
I'm currently watching Age of Youth. It has to do a lot with friendship, school/college life, roommates, personal issues, etc.
Hope you feel better soon! :)
