From the clues and older Chapters it seems he’s just grateful to her and so is his family, so his way to repay her is by “reciprocating” her feelings, even if he doesn’t feel that way romantically about her. I wonder if he’s in the closet (gay) or if he’s just aromantic. People who are aromantic have very little to no romantic feelings or care for romantic relationships. Maybe either of these reasons is why it was easy to just repay her saving his dad.
