It's all fun and sweet until a bad man shows up. I liked everything about this story. From Kajima and Hiro's seemingly hot and wholesomely cute relationship development, to the side characters that added vibrancy to the story, and the deep drama that was caught at the climax. Somehow through it all it still continues the flawless flow progress in which concluded as how it started - being fun and sweet. The mangaka liked how the bad guy somehow got his redemption arc by doing things right in the end, but based on his past actions I would've appreciated if he was dealt with accordinglyon what he has done, and that's where he gets to correct his life afterwards.
