This manga is very emotionally raw and real, at least in my experience. I can relate to her in many ways.
That sense of suffocation and isolation can make people do stupid things--as seen with all of the main characters in this series. Sumire feels alone and suffocated after her ex-boyfriend cheated on her and impregnated another woman. As unlikely as it is, who doesn't yearn for a convenient, stable, pure, supportive, and genuine connection with another human being during times like this? Someone who understands you and keeps you sane, with no real strings attached?
Enter Momo, an emotional support dog in the shape of a human boy. Momo understands that what she needs isn't a boyfriend but a safe-space she can easily retreat to without pressure/chitchat. In a real relationship, both partners have to put in high levels of patience, communication, energy and time, but she's already too exhausted to insert herself into a serious relationship (hence momo, hence the lackluster relationship with hasomi).
I can see why Sumire refuses to see Momo as a full-fledged human being with his own feelings and troubles. She isn't guilty dating guys while having Momo in the house because Sumire is too stressed out to spare the emotional energy needed to think about Momo as a partner on equal standing.
And that's what I love about this manga. It emphasizes from ** chapter one ** that Sumire's thought process is ** flawed . Momo is seen hurt by Sumire's lack of consideration for him, even though he naively thought he'd be ok with being just a pet at first.
Convenient unconditional love does not exist, and this series explores what it takes for Sumire and Momo to realize that they ** cannot ** simply keep using each other as a "safe haven"... that emotional intimacy ** does come with strings because we are humans after all, not dogs (or saints). We can't just expect someone to happily invest time and energy in us if we can't do the same.
This manga really sympathizes with the troubles that relationship-phobic individuals struggle with...that need for easy but authentic emotional intimacy in their lives even after they've been burned by a previous romantic betrayal. And I respect that. It's a huge problem in big cities. Young adults who are forced to spend all their energy pursuing their careers can often end up isolated from their communities, especially if the career is in a competitive field. Not simultaneously juggling a job and a relationship at the same time means you might not have the support you need... and the author showed that really well through the main female character.
As for ** Hasumei **, he was the representation of surface-level perfection that MC felt like she needed to have since her last boyfriend had an inferiority complex and cheated on her. Unfortunately, the MC doesn't realize that, in the end, she doesn't feel fulfilled with him because it takes too much emotional energy for her to open up to Hasumi. And then before she knew it, it was too late.
The ending fell flat for me, but overall the story really resonates as a fellow stressed out adult trying to keep everything under control while keeping the suffocating isolation at bay.
