Chapter 1: I definitely like the idea that he doesn't intend to do anything but waste some time. Yet he finds something else worth his time.

I think to improve this you could go more in depth for the emotions. Give more as to what Sehun is feeling. More physical responses would allow his emotions to be matched with the audience when they can recall the same feeling or symptom of emotion. A kiss obviously means attraction, but just alright? I think you can do better than just that. It doesn't explain how it feel alright? Does it mean he's less anxious or content or hopeful?
