To begin with, I watched it quite a long time ago now, so I surely forgot lot of reasons why I loved this title so much. All you have to know is that I waited every week impatiently for episodes to come out and had my heart to flutter for each episode, I liked all episodes and have not been bothered by any of them.

Now I'm going to list a few resons for why I loved this series (sorry it won't be a well organized review):
-The characters are extremly loveable. I felt attached to the four main of course (Hands down to Hashimoto-san who is my favorite character, so cute and funny, I lowkey want to marry her) but also to others like the side couple doing fun things or the mother of Ida. The relationtions between all of them are well written and I especially liked the building of a real friendship between Aoki and Hashimoto, this is such an iconic duo. And for once the girl is truly kind and, even more rare, she is not at all a threat to the development of romance. At every interaction it was a pleasure to see.
-The series is funny and cute. A lt of scenes were pure amazment, Ida and Aoki had adorable scenes that were so romantic and beautiful to see because of the setting. It was also the case for the side couple whom love story was really well-developed and whose story I was deeply invested in. BUT the interest of this series also relies on the comedy aspect. I already talked about the great comic-relief duo that is Aoki-Hashimoto but a lot of scenes also are funny by themselves. I laughed out loud at some moments.
-serious subject were also talked about, and not only the usual way. What I mean by that homphobia is shown from an interseting aspect: hidden, not only frontal (if it makes sense). Whether it be by jokes meant for no harm or a character that seemed nice but ends up having prejudices. And it's all the more important to show that homophobia can have many forms is that we can see characters really hurt by those situations but kind of "gaslighting" themselves because they deem them as not being "that important".
-To end this up with, one of my favorite point: the mature relation of Aoki and Ida, they communicate! Share their worries, show to the other they're here for support, care for their partner, etc. I loved to see them evolve in a really cute and healthy way :)

To sum it up: a really cute and fun story that still have important subject treated. To see and see again.
