I read Kimi to Parade yesterday and accidentally stumbled upon this manga today. For a moment I thought I already read the same story but Kimi to Parade was their story from 10 years ago. I guess you should read that first before this one. Also I really love the story a lot. It's not overdramatic and it isn't that cliché as well. Just enough to stir your heart out of calmness. I really like Akaboshi even from the story Kimi to Parade. I really like how he views things despite not being able to be with a lot of people.
