Overall I thought this romance was fine. I didn't like it as much as everyone did, but I can understand why it was so well received.
First of all, I like this theme of the male lead, Ichikawa, being a massive overthinker and continuously making assumptions about what Yamada, the female lead, is thinking, just so that he doesn't get hurt later on. I know it's a common theme but it's done well here. I like the soundtrack and the direction from Akagi Hiroaki (director of Teasing Master Takagi-san).
But I personally don't like this much fanservice in romance. It makes it difficult for me to take the bond between the characters seriously. For instance, there's a scene where Ichikawa is sort of put off to see someone else talk about the physical features of Yamada. But then after that episode, there are so many moments when Ichikawa himself is thinking the same things about her. That really makes me wonder if he just likes her for her appearance. As a viewer, I wouldn't want to spend my time on a romance that's just based on appearance.
Similarly for Yamada, while it was sweet to see her try out various ways in order to spend time with Ichikawa, we are never really told exactly why she likes him.
But this show did get better as it went along. The bond between the 2 characters got sweeter episode by episode, especially in the second half. So I'm looking forward to the progression of these characters in season 2. - Talking_about_anime
