Instead, he shows his love through casual actions or words that slip out unexpectedly. Extremely devoted. Cheating is absolutely out of the question. Not a morning person. However, he never skips school or arrives late. He attends properly. In the morning, he likes commuting while listening to music through wired earphones. Good at sports. Also smart.

Apparently, he practiced hard because he wanted to see a happy face. He doesn't get clingy in public, but when the two of you are alone, he gets a bit closer.
