I have to wonder about the patreon comments because this update was the best so far for me. I've watched people play the other character's routes and the writing is good but it was Haruki that made me buy the game for myself. There may be spoilers in my comment.
Considering what the other routes have happening them, especially Shoichi, I feel like What Haruki did wasn't too much.
Remember that there was a long buildup to this. The past update had me squealing and blushing for how cute they looked next to each other. The emotions Yuu felt leading up to this, the drive to push through all the smack talk to get closer to Haru, going out of his way to make time to see him, doing anything and everything to get to know him better....you can see the attraction. Especially in that moment at the end of last patch. Definite spoilers ahead.
With Sho you can see how its a little awkward to Yuu being as they've known each other all their lives, it took getting used to and being overwhelmed from Sho's forwardness is very different from how Yuu pursues Haru. This route shows Yuu wanting it before having any confession. Growing more comfortable around him and realizing his feelings first before anything happened.
The warmth and sweetness that built up to this, the patience that Yuu showed to learn how to interact with Haru up til now really payed off in this patch.
I can't see Yuu doing a 180 and feeling uncomfortable after the fact cause he already felt thirsty for Haru before it happened. Its okay to want that control taken. This route is a very healthy route compared to the drama and pain in the others, so I can see Sho having some beef if it comes to that. I just hope that going forward haru is more touchy feely. I look forward to the drama with Sho and how they maneuver that bit. So unbelievably exited for next update! HaruXYuu is my OTP!
