Hopefully in the future we can get some romance with him, don't want him to be corrupted just to see some lewd scenes with him.
He'll be affectionate with you when you visit and leave his house when you have 3 hearts. But yeah, the workout will change and it's just about two lewd scenes when you make the correct choices. I'm not complaining about it, it's a hot scene, but I hope they do make some choices to spend time with him. Like a nighttime walk (since he doesn't like to be confronted about being together), in the woods, spending time at your house in a Bareshade again for some beer, or just a hot spring since he does a lot of workouts and works. I love it whenever he gets flustered and embarrassed. It's a nice thing to see a big, hot-tempered guy like him getting flustered.
