Man, this is way better than I was expecting. I mean, the first chapter was decent, but I expected the plot developments to turn bland from the second chapter on, like say, have the heroine just fawn over him constantly simply due to that 1 time he saved her while he just constantly runs away from her, but instead it gradually builds up their connection.
Technically, it's still developing fast by most measures, since her guard is so loose than she wanted to visit his house, but since this is based on a web novel, I half-expect it to actually take the relationship places rather than have it stagnate at deredere fanservice, so this level of relationship advancement in 2 chapters isn't a red flag at all.
To me, the ideal way to develop the story from here on would be to develop their backstories mutually, have them affect and change each other in positive ways, and also mix in romantic tension or fanservice, but I'll try not to raise my hopes too much; I'd be happy with a slow-paced love comedy, anyway. Still, I'm hyped for more chapters, and it's rare for me to feel this way after only 2 chapters.
