Nani mo Iwanai
It has complicated but interesting stories. Some of them were a little dark but the 1 one has the most interesting plot. Because we can see those character had some... issues, but they don't do anything completely "evil" or even something I have never seen before. I've seen plenty of girls go for sneaky tactics like those to "steal man" from each other or manipulate them, so it's interesting to see it from an outsider perspective. It hits you how powerful the act actually is and how we chose to soften it in real life.

I feel like the first story has a lot of potential but it was handled really badly. I also would've loved to see a little more of the relationship between main character and his father
Haru no Nioi
It was cute with interesting stories but maybe a little too short
Make Me Bark
It's not like the best story in the world, but it's kinda cute, ukes in this manga are really erotic and the couples have a strange but good dynamic... I mean it works, you kinda get why they are together.
Wakaki Taketora-kun no Nayami
Really like it. Interesting and funny couples. Taketora was my favorite character, he is like sooooo cool and adorable at the same time! and I didn't really liked the musicians too much.
Taka to Tonbi to Aburaage
I found interesting how they talked about relationships. That line about confessing because he wants the relationship to remain the same it's very powerful. Also the respect about wanting to please people expectation is an interesting view too (Very japanese). The relationships are a little cold though. Not that much satisfying.
