This picture sums up this manga perfectly. The main characters are in the middle which makes it seem that they might be the main focus of the story but if you look at the picture as a whole you notice that the side characters make up about 80-90 % of the drawing.
I don't despise this manga but keeping myself from dropping it after the story got sidetracked so hard that I midway through the manga forgot who the main characters of this story were was hard. I wouldn't mind if the story was about the school rather than shiramine and kurosawas relationship or if the sidestories were actual side chapters.
This manga really started of strong with two good leads and a not very unique but interesting enough setup for their relationship but it diluted into an utter mess of sideplots and sidestories that have little or nothing to do with the main story except the fact that they go to the same school.
