I don't know if their relationship is "healthy" to be honest. They got into a relationship after one of them finally got out of an abusive separation. Like aside for that experience, does anything else keep them together? Do they even like the same things, etc
Well, they did talk quite positively about each other, both of them like the other's personality. They also seem to be compatible, what with Fukami liking to take care of others and Miya having a dependent personality. They didn't jump into mindless sex and declaration of love immidiatly after Miya got out of the abusive relationship either, so I don't see a problem on that front.
I know this is fiction but if they were real people I’d caution them against codependency. It may seem like it’s good and all now (to some; I didn’t like the sex scene I felt like the feelings were forced), but as people grow and change so do the dynamics. If what brought them together was Miya’s trauma and whats keeping them together is the aftermath of this trauma, that’s just not a solid foundation to a healthy, long-lasting relationship. Anyways just my two cents as someone who is in psychology.
Wow, they have such a healthy relationship :O is it bad that I kinda expect yaoi characters to force kisses/sex on their romantic interests even if they say no ? Don't answer that, I know it is... Proud of this manga for not resorting to that but still being interesting!
