Yui appeared to be about to express her affections to Hachiman at the end of their short date, but an incoming phone from her mother cut her off. Despite his regular anger with her, Hachiman demonstrates that he enjoys his time with her, albeit he may not see her romantically. This leads us to believe that they are a compatible pair. Hachiman is a popular boy at Yui's school and she seems to enjoy being with him. She also calls him her "gentleman friend", which implies that they have a close relationship beyond just dating. We can assume from this information that Hachiman likes Yui too and wants to take things slowly with her. Hachiman comes from a rich family and it seems like he wants to show Yui that there are other things in life than just money. This makes him the perfect boyfriend for anyone who wants to spend time with him but not get tied down by financial worries.
