Two things should be noted here:
1. This takes place in the same school and around the same time as the first season of "Lily", the author's other main title. One or two side characters from "Lily" pop up every once in a while.
2. The series goes up to 200 and is then on hiatus for who knows how long. If you want to get to the end faster, you can find it on WebComics. There's what may or may not be a cliffhanger ending, and the author says they'll continue the story, so here's hoping it gets more updates soon.
It's light shoujou ai, so don't go in expecting full on romance by the end of it. There is a reconciliation of feelings by the end of the season, but this author looooooves a slow burn. (Lily took over 100 episodes to get to the first kiss.) So grab a snickers. It's still a good story, and the ending isn't rushed, so it appears the author has a clear path for the story to take. But it's going to be a bit of a trek.
