I see, so, something kind of like Cid in Eminence in Shadow where he just doesn’t care about others romantic feelings.

I’m not sure honestly. I don’t get the feeling that the party has any romantic feelings for MC. At least as a whole. There are two characters where I could see them having a crush on MC but it’s certainly not something explicitly spelled out. I see it more like how a daughter would be possessive of their dad.

I remember one point where the other reincarnate pressures MC into marrying her when he doesn’t find someone in X years and MC goes “yeah, yeah whatever” and another girl gets involved in this as well without being against this. So I can see this being open to interpretation for those two. But given how obvious it is made for other characters outside the party when they have an romantic interest in MC and how you have to read between the lines for those inside his party, I’m fairly confident that they have familial love for each other rather than romantic. At least not more than a childish crush.
