- No, they don't have a kid yet, because they just got married in the latest v13 of LN (think its near the end of it, but can't be sure as lack of translation).
- As for whether MC loves her or not, well technically MC didn't really love Aura from start either. Yeah he liked her prior to his marriage, but his love for her only blossomed after marriage (before that it was just attraction). Similarly, MC here doesn't really hate Freya and does hold some feelings of respect towards her. As for whether the love truly blossomed or not, well like i mentioned earlier, because of lack of translation, there is no info on that (current translation is at LN v09, with a full chapter getting translated in around 2-3 weeks).
- Also, i can't really give info from WN either, since it was discontinued by Author once the LN was published (from what i remember before it got axed, Aura's focus in the WN wasn't "Glass", but rather the "Chain" which was on MC's Cycle which he had at first).
