Confession baits and misunderstandings are the lowest of the low. If you're starting to write them as an author, stop and start considering retirement. Like this shit would never happen in reality, NO ONE is that dense, so it only annoys the readers and serves literally no purpose.
And no, writing "Is this a teenage manga or something...?" in the next panel does not erase the fact that you wrote a garbage scene. This is bad to the point where I'm considering dropping this just because of it, because there's no guarantee the author won't do this shit again.
