It's a bit concerning to see some people don't see the issue with the current route update, and dismiss the critiques I've seen here.
SPOILERS AHEAD
The scene itself, it's hot, it really is, even I can admit that. The thing is, it feels like Yuu's character got assassinated somewhat, and didn't stay consistent with whom he really is. Amongst the other routes, Yuu has always been the conservative type when it comes to showing his sexuality, he may oogle, he may peak, he may glance to check someone out, but he would never do something so brazenly as give someone oral in public, in their school of all places.
Yes, he may be dense and slow at times, impulsive at worst, as seen in Shoichi's route where he kissed him infront of his house without taking into consideration if his dad was even there. But this way far beyond that. He did something so risky, borderline expulsion worthy, in a school, where his entire career, his future, his reputation, not just among students, but his friends, hangs in the balance. Which we have seen, he really deeply cares about, he wants to go pro, he cares alot of his friends, and especially his family, and certainly wouldn't want his sexuality to be outed, worse, with an act like that. And, going back to Shoichi's Route, it's been established that he doesn't like to be pushed to do something he doesn't want. And that was in private with him. What more in public, in school, just barely out of sight from the rest. (Yes he did mention this would've been something that we would've been disgusted by, something he would've hated, something he wouldn't let happen to himself, and yet he still went with it. It feels so, disingenuous. Especially after building up what kind of person Yuu is)
Honestly, throughout the entire route, I've felt as if everything else in the story got a backseat. His family, his friends, his passion for tennis, his mental problems. Everything was pushed aside, so that the focus would be entirely over him gushing and being obsessed by Haruki. (Which, I don't take issue as much, I do find it cute, just as long as everything else in the story didn't also get shafted for it. Because everything seems to happen "behind the scenes" and just delivered to us through exposition and dialogue. It would be nice if we get to see the other stuff we see from the other routes as well, but this time with we get a few unique interactions because it's in Haruki's route.
All in all, I still like the route (maybe a bit less now, but still leaning towards like at least), but I do hope they do make it like in Shoichi's route, where he slowly realizes that it's not something he actually wanted, and has a talk with Haruki about it. Or at the very least, have him ask for his consent first before he does it, or let him lead like in Shoichi's. Because yes, Haruki is different from the other characters, but as it stands, the relationship looks very toxic, because if everything went horribly wrong, Yuu is the one who stands to lose the most from it.
TLDR: Yuu's Character feels assassinated throughout this entire route, I like the route still, but I hope they would keep some aspects of Yuu's personality and important character key points intact throughout the route, and also make it so that there's a revelation in a later update where he realizes its something he didn't like/let him take it at his pace and have a talk with Haruki.
PS. The Roughness of the scene doesn't need to be lessened or cut out entirely, like I said, it was hot, and I understand why the route took that direction. But at the very least, give Yuu back his character and personality, the one we've come to love. And give the route it's key moments for Yuu's development and not just make it about him being with Haruki
