I definitely did not realize the slow-burn pace you were going for in regards to relationships, just because of how quickly players are given the option to actively flirt. Most of the response I would have given is now void given your decision about the ages, but I will say that I'm sorry my comment presumably had to be what pushed you to make a decision that is now giving you more editing work! I know the pain. Nevertheless, I'm definitely in favor of the change.
In regards to your question about specific scenes, I think Zanetta's flirtatious teasing currently comes off as slightly over the line in the scene where the MC can ask her about her family. As a 20-year-old, I know I wouldn't ever assume a high-school-aged kid was trying to come on to me, nor would I (even jokingly) engage in teasing one flirtatiously. In my opinion, this is essentially absolved by changing the MC's age to 18, but I figured I would mention it specifically just in case you still wanted to know. It's definitely not egregious, but I for sure had the thought of, "Excuse me, ma'am? This is a high-school-aged child!"
I didn't see any other red flags in my speedrunning all the romance scenes, though! Ajmal's freaking out when confronted by a perhaps overly-forward MC feels very realistic and reasonable given his...rather complicated situation, and I think that attitude could easily carry over to an 18-year-old MC. After all, they're still a ruler (and probably somewhat intimidating as a result) as well as a slightly-younger childhood friend, which in itself presents all kinds of delightful possibilities for emotional turmoil.
But, overall, I'm really glad my comments didn't come off the wrong way. I'm looking forward to the update, and I wish you good luck with writing and editing!! I'm really loving the story so far, and while I don't go on the interactive-fiction side of tumblr much, just to avoid all the behind-the-scenes character spoilers, I gave your page a follow and I'm excited to be along for the ride. :)
