Not gonna lie, if this was the last panel, it'd be a better ending than like... 95% of rom com manga out there. No theatralics, just people being honest about what they feel, and they go off into the sunset.
If this is the halfway point of the damn manga and we get another 24 chapters about their budding relationship up until the wedding... That's the other 5%.
There's a chance for true greatness here!
