The manga starts with explaining how childhood friends Takeuchi and Umezawa fell for their classmate Youhei. They become rivals after learning their feelings. Takeuchi has asthma attacks and misses school, that affects his mood a lot. The manga flows fast and is interesting enough. It gets better as you read more. The art uses contrast well and it's pleasant to the eyes. The characters are likeable. I was satisfied with the ending, it was the best way to end the story. It was a interesting manga about friendship and love. It doesn't take that long to read so I recommend you give it a shot!
