Some people in the comments going "oooh, Tomoe left her kids to travel the world!"
As if she was on a journey to fill her instagram with #travelgoals
She's a photojournalist. That's a very dangerous job. They even thought she died at one point. And that job takes greater passion than many realize. It's not like an everyday office job. You can't just call it quits when you know you are trained to show the truth from around the world. She can't bring the kid around with her. She wasn't even expecting to get pregnant. She cant pretend like she can play the role of a mother. Leaving ayu with Kazuma and chiaki was the best option for her to make.
Plus, it's not as if she did it on a whim either. These guys are more than just her friends. They are her brothers. She knows they will accept and love ayu. She trusts them the most. In fact, they even felt like tomoe could still see through them. She knew that, despite being as unprepared as she is, they can do it and built a loving home for ayu.
Plus, it's not like she completely neglected Ayu. She obviously has a loving and gealthyrelationship with her.

She choose to have a career like that, and abandoned her child to her childhood friends without caring about their needs or her childs. Yes she likely sends her child money every month, but this still doesn't free her behaviour from criticism. She's fortunate that her friends agreed to take care of her child, and have zero legal protection as they aren't her guardians, relatives or formally adopted parents. Tomoe could have her child removed from her care due to her abandoning her. To add insult to injury she returns years later, she's a stranger to her daughter who now has a secure environment with the two male characters and disrupts this by expecting her to go live with her.

Ok, things that you missed the mark on.
1. It was implied that she had that career before she got pregnant. What she didnt expect was to get pregnant. She couldn't being herself to abort since the baby is all she has left of the man she loved.
2. She wasnt a stranger to her daughter. Ayu called her mom as soon as they saw each other. In case reading comprehension failed, it implies that the daughter knows who she is and that tomoe frequently visits. Even Chiaki asked "for how long are you around *this time*". Meaning, she's been coming back ad forth to visit.
3. Some cultural context here. Unlike western countries, Asian countries are actually more lenient in guardianship matters. As long as the child is being well cared for and the surviving parent gives consent, the child can stay with who she/he recognizes as their guardians, leagl or not. Yes, this was the case of my cousin who lives in japan. O yeah, I know some stuff. Their government doesnt readily take away a well cared for child without thought.
4. Where did you get the idea that she took away the child and expected her to live with her? They let the child stay with their mom while she was in japan. Sort of like a sleepover. It wasn't a permanent arrangement.
5. I agree with you that she could have told them better, but like I said, she knows these people to the core. She knows they can handle it. She knows it won't make their loves turn out for the worst because she grew up being on the receiving end of their care as well. She lost her parents at a young age, and no one prepared anyone for that. Yet Kazuma, Chiaki and their families helped her out. And she knows they'll do the same thing for her child. She didn't abandon her eithout thinking of her child's needs. She left her child in their care bacuse she WAS thinking about the best for ayu.
And Ayu is growing up healthy. You'd be surprised that many people irl grow up the same way and grow healthy and happy all the same
This is actually my experience as well. I grew up with my "aunt" while my mom was working in the US. And never once did I feel abandoned, especially since I kept in contact with my mom, knew how much she worked hard for me, how much she loves me, and, whenever she came home for a while, I would stay with her as well. I had no troubles growing up. When I reached teenagehood, I got to be independent and my aunt didn't have tk shelter me as much. I also call her my second mom.
Look, not everyone is bound for doom when their lives are not as textbook normal as you're projecting. In fact, we end up more resilient and more open-minded.

She dumped her kid on her friends, so she could go off swanning around the world choosing her career. The child was essentially brought up by the friends and was given stability from them. Despite them not being formal foster parents, meaning they didn't have any legal security or government entitlements. Tomoe then waltzing back to play the good mother, as if abandoning your kid is acceptable. What would she have done if her two friends were unable to take in her child? Their own relationship and careers took a hit due to this arrangement, they may have decided they were unable to cope. It was rather arrogant of Tomoe that she expected them to parent her daughter like that.

Even in the US these situations occur. I know a woman who was unable to take care of her son, and gave guardianship to a friend (I.e. power of attorney) while still Having visitation rights. You see this in the military as well.. there are single moms and not all of them choose family members to take care of there children during there deployments.

I’m confused, what’s your deal? She didn’t abandon her kid, she left her with her friends, while staying in contact and the said friends were more than willing to take care of the child. I’d rather have her following her passion and taking care of her through guardianship, rather than a shitty mom hating her life, and oh, let’s not forget project her misgivings on the child. The child has three parents and from what I’ve seen, Tomoe’s kid actually completes their family (e,g standing up for her parents when they are feeling insecure etc..,). To put it bluntly (and I’m sorry if I’m rude), grow up and look at the world with a broader viewpoint. Your conformist views are too damn narrow and selfish for unnecessary reasons.

In this scene, my heart just flew out to Toshio.
Such an interesting story and so promising premise.
Looove the main character, teaching about human rights. And Toshio, such a precious soul.
I want to see more and I hope the stupid people in that company get hit with karma.
I get really teary eyed everytime he apologizes for his stutter. No baby, dont apologize :'(
