So firstly, anyone going in thinking you can compare it to modern-day anime will probably be disappointed, the art style is more unique and not something I've seen too often, but it grew on me and I feel like the story wouldn't have been the same if it were any different.
The plot and art style are very alike, in the way that both look very mediocre and a bit dull at first glance, but the more I watched the more it grew on me. Don't go looking for an immensely complicated or emotional storyline, cause it's very simple, but it is cute.
Due to some reasons, I was expecting to stop the anime at some point due to aggressive behaviour, which unfortunately can be found in BL for some reason. But that was not the case, there really is not a whole lot of fan service or anything strange going on, although you can never have enough consent - for which I wholeheartedly stand - to me, it ended up very wholesome and I enjoyed it - once again..not a masterpiece but not horrible.
Anyways, in the end, everyone has their own preferences and likes, if you do end up watching this as a BL fan, I hope you also enjoy it.
