Isn't the mom is evil? Why her react like that?
Based on this chapter, it seems like she and her planet are trying to remain neutral in Daxia's factional struggles, so she neither gets her (gotta hand it to him) husband metaphorically (via space fleet action) or literally NTR'd by the MC, or gets her planet and possibly herself plowed by the Dragon Slayer Alliance fleets, and she's very worried about her daughter being on a planet controlled by a Dragon Slayer Alliance aligned regent/dowager empress, since she believes that the Dragon Slayer alliance is probably about to completely secede from Daxia, and she's recklessly trying to get her daughter back to their home planet before this becomes a civil war.
Admittedly, the political situation isn't incredibly well explained in this manhua, but that's what I think the current situation is.
And she seems to be very interested in having grandchildren, as long as they have her family name. Also, just generally completely ok with interspecies romance and star-crossed young love (which explains her daughter).
