This review is truly full and complete with spoiler!

Just to put it out there, Eiji and Makki's age difference and stuff is fucked up, I hated it, but I sometimes, in order to enjoy a show, I disociate from certain facts while I'm consuming the piece of work, so it's not being taken into direct consideration while writing my next thoughts but it's yikes of the story and it needs to be mentioned.

I'd like to go step by step with my feelings on this serie, as they changed a lot during the course of the story.
First, isn't the synopsis kinda missleading? Or maybe it's the fact that I didn't read it ith that much attention? No idea, but the thing is that I LOVED the first 3 episodes (more or less, not sure of the episode, but 'til the christmas part), the way they interact the 3 of them, and kinda build a family, and even tho Eiji and Makki r a couple from a certain point (I love the naturality in which they r shown to get together,), it feels like the 3 of them are complete when together. It's not named directly which is a shame but Meiko is clearly ace and, as an ace person myself, I found so beautiful their relationship in the way it felt like the friendships where as important to each other as the romantic part. I could totally picture them still together celebrating christmas for many years to come, and maybe that's part of the reason the next part was so sad and kinda dissapointing to watch for me.
So, after absolutely loving all that, things kinda start to really go south imo when Eiji decides to work in his dad's company, because it shows who Eiji is trying to win his dad's aproval in expenses of his own desires for the future. But then it's the real shitshow when in response to the dad wanting for them to break up Meiko proposes to have a baby, and not only that, the both of them agree. First of all, I really am with the characters in thinking that neither of them was more at fault than the others, the 3 of them made the dumbest posible choice and just went with it, Meiko is forever lying to herself by saying she's ONLY doing this for them, bcs she doesn't want to watch them suffer, when it's clear she's doing it for herself (maybe it's also thinking of them at a level, but surely not exclusivly and totally), because she can't stand to thinking of her family breaking apart, and loosing them, and I think, in not realising that in time, she's unable to see the mistake she's making. The other 2 can be more simply described as dessperate and dumb, Eiji bcs he refuses to give up on anything in a situation that's sadly not gonna hold that, because we live in the society we do, and Makki's dessperation is the more simple a in a way, because he's just holding on to the people dear to him and is willing, in that moment, to do anything for them. All that to say, at the end of my long and dedicated analisis, the choice they make is so unberably stupid it's unrealistic, like, the thought process makes no sense whatsoever, like, how in the world did they think them coparenting a child they concived by sleeping the 3 of them together was gonna change the mind of an homophobic shit like the dad, they definitely weren't portraied as being as dumb as they ended up being (future me commenting that i now realized the original idea was for her to be a surrogate mother but the logic is still very flimsy, was rapidly forgotten and most of all, nothing is changing how i felt in the moment of watching all that). Other thing that i'm actually so glad Meiko mentioned, it's so awful to use a child as an instrument to your selfish desires, and the 3 of them are guilty of that.
The rest of the show get it's sense back and wraps up nice and logically, and that was a relief after the thing before. I found pretty that Makki eventually findis someone who loves him and (i think), he feels deeply for as well, even tho they clearly have lot to go yet in their relationship. I also liked that by the end Makki and Meiko were able to get at least a semblance of their previous relationship, that may never be as profound as it was, but it's stll beautiful to watch friendships persevering over time, and that part of this whole story that stuck to me more inmidiately. Finally, Eiji's ending was so very sad and heartbreaking, because one second it feels like maybe he is content and satisfied with his loved ones (who he truly truly loves) and with how his life turned out (maybe it was wishfull thinking on my side, wanting his ending not to be as sad as it is),w but then as we watch him break in tears it becomes clear he's not only not over Makki , but also afected by the more profound realization of his reality of being a cage in which he's never gonna be able to be truly himself.
