I couldn't understand Miho and Nao's relationship it's just weird

They just have an open relationship. You might be surprised, it's pretty common nowadays. I know a few couples, even married ones, who do this. There are all different types of love (eros, agape, philia, etc...) and there are some people that get that with one person while there are others who get it from separate different people. Either way isn't strange or wrong. They can just separate the concept of love. We just get the love we want a bit differently.
As long as all parties consent and are in knowledge of the relations, it can be healthy and fulfilling as a closed one. People in open relationships have an agreement that having sex or emotional relationships with other people is OK.
And usually open relationships are thought to occur between two people in a primary relationship who have agreed to open up their relationship sexually — but not romantically.
And I think that's how it is for Miho and Nao. I think they agreed open up their relationship sexually but not romantically.
And like how a previous comment said before, Miho just accepts that Nao sometimes have sex with other people but Nao still likes her.
Idk maybe Nao wants to explore his sexuality with someone of a different gender.
Maybe Nao and Miho have a case of mismatched libidos.
Maybe Nao really likes it from the back and want to keep exploring that but Miho just have no interest in that.
I think Miho understands that Nao loves her and that he also has physical needs that she can't/doesn't want to provide (like he wants to be fucked) and so she allows him to have physical relationships with others to satisfy his sexual needs.
I mean it could be countless of things. But as long as they're both in agreement, I don't find anything wrong with it.
Also I actually think it's pretty awesome how chill Miho is with it.
Oh but I've never been in an open relationship and they're not for me, so everything I wrote above is just my thoughts on this.
I hope everyone change their rating cuz this manga doesn't even deserve 7.5 ☆ rating
