Ffs just confess already, you literally did it before why are we repeating the same relationship step endlessly...
Seriously, the annoying thing with romance manga is that authors only knows how to write about stuff before they are dating...
They don't know shit about the dating aspect itself so they just make it the very final scene so they won't have to think about what to write about it....
This is the reason why manga like Fake Harem are more popular, it has the best of both world, pre romance and romance...
