They might be very different, but along with Jun, Haruki is one of my favorite types of character, so it's really nice to finally have a route for him. "Bad boys" with depth just make me feel all warm and fuzzy. and I do hope we get to fk him someday cuz he's very cute tbh
I'm not sure how to feel about the way his route was integrated into the story, which came a bit off as a series of very convenient events (though I can see how this is somewhat necessary for a "secret route" to even exist here) and Yuuichi suddenly getting a little bit too interested in someone he didn't even perceive as a good person for the longest time, that part felt very dating sim-esque to me, if that makes any sense, but beyond that, it was very nicely written in my opinion, and along with elements that have already been established about Haruki as a character in the past, there's definitely enough depth to him to make for a very enjoyable route, and even for Yuuichi to grow quite a bit as well. Heck, he already realized how judgmental he can be and the route just started, so yeah, very good stuff and looking forward to more.
