So, I read everything out of order. It was Kimi ga Koi ni Midareru first, then this, then lastly I'm going to read Kimi ga Koi ni Oboreru - they were all on my "to read" list and I hadn't realized there was an order.
Comparing it to "Midareru", this plot felt like exactly the opposite. While "Midareru" was full of twists and surprises, this was very predictable, but in a great way! I was thinking "wouldn't it be awesome if this happened?", and then it turned out to be this series' main twist. But it was the kind of expectation that builds with the anticipation of when you know something is coming that you really wanted to see. But Takanaga-sensei basically touched on every cliché I love and it also did its job of having me crying - which is a must for BL to be good.
The characters were also very different from my previous read. While Yuzuki is a fragile but surprisingly assertive uke, Haru is more of the pained but responsible type. Neither are my type and I did see a pattern of crying a bit more than I'd like the ukes to, but their personalities were both done in a way that made me enjoy it.
Also, while Kijima is more reserved and not so good at communicating, Tsubaki is straightforward and reckless. I loved how well she portrayed their age gaps, and that goes for all the connected stories. Maybe I'm getting old (the tween, teen and adult me reading BL feels different), but I definitely noticed the difference between a story set in high school and one with two adult males - also, Tsukasa's personality is very teen-like. He's impulsive, brave, emotional. It's refreshing to see that so well done.
The art was, as usually, great. And though it didn't captive me as much as "Midareru", the jealousy bit was just heart-wrenching! I wish every manga had a chapter about the seme's jealousy, I really love stuff like that.
While I gave "Midareru" a solid 10 star rating, this one had a few things I disliked, and therefore it won't be full score. The pace was good, but it could've been a bit less rushed - this series should be just a tad longer. They fell in love too quickly, the conflicts were presented too fast...even Tsukasa's love was confessed too early, and no explanation about their past and how he had fallen in love in the first place was given.
Also, I'm not particularly enraged by the sexual advances like many people are (really, people, aren't you used to it by now? Don't read BL if you aren't), but I don't really care for it either, so that first scene of Tsukasa's "attack" could've stopped with just a kiss. The others were all fine because Haru was just reluctant, not really against it.
Another issue was that the teacher-student relationship issue was never even brought up. Same as when characters don't dwell upon their sexuality (which, again, happens here - and could've been dealt with the in the same manner as "Midareru", which a dismissal in conversation, but should absolutely be addressed), it doesn't have to be the focus or even discussed for long, but it does have to be solved - which did not happen here, as it was never even brought up.
I'm ready to read "Oboreru" now, but I have to say that at the moment I really dislike Reiichirou, so I'm going to start that series already annoyed by him. So far, he broke both Haru and Kijima's heart, and he seems to be a heartless, cold bastard. Which will probably make it much more enjoyable, so here we go~!
