I personally don't think any of the Yuma routes will end in hard NTR. While he does get possessive when horny, he's always apologetic afterwards when he calms down and it would feel out of character for him to actually steal Hana away if Tatsuki doesn't like it. I think FE is delaying it because it's the last of the unfinished Yuma routes and he's anticipating that a bunch of his subs don't care about Katsuo and are just waiting for the Yuma stuff to be complete before unsubscribing.Oh yeah you're right! Well he's probably saving that to implement hard NTR in the holiday season. People always try to end the year on highly anticipated content.
