nah, it's at best implied. i thought i was overthinking it too when miria and ryder were discussing the concept of parents, jair's mood suddenly got a little intense and he even crumpled a piece of paper, i initially chalked it up to him being envious of them bc he wanted to be mori's parent too. but jair specifically interrupting this ambiguously romantic mood later on is a deliberate choice. which recontextualizes his weird reaction in the earlier chapters. but if im wrong, then im wrong. i would be happy to be wrong. BUT if there's romance progression happening again, and jair is involved in the scene again, then that's basically confirmation.

i guess i the only one who doesnt like the romance and jair's implied feelings for miria (as it could result in unnecessary love drama), i feel it falls into the outdated "he's man(ly looking) and she's a woman(ly looking) so therefore it's natural they will get together" trope. i mean, is it even possible for genderless aliens who dont produce sexually to fall in love? also, dont understand why people are calling ryder the dad since the whole point of the story is that everyone mori came across (the wolves, his redhead friend, aiya, ofc miria and ryder, the fah servants) are his moms
