Hope this just develops into romantic feelings and lets it be than getting aware of their feelings and getting all awkward and hes going to decide he'd just confess and ask her out.
that feels more rewarding to read than reading 100 chapters of preparing to confess. imho at least.
Wait, shit, I can already see the fucking ending. She's going to be sad that she couldn't steal anything from him and he's going to say something like "oh but you stole my heart", and then boom, the end. Maybe an omake if we're lucky.
