One of those stories where the author is being self-indulgent instead of trying to create a strong plot and characters. See it in fanfic all the time too. It very obviously lacked the support of a good editor.
That is one thing I feel traditional manga has over webtoons. It typically has to be resolved in five chapters and the editors and publishers are always breathing down the artist' neck.
omg the kid version of the uke made me laugh. so unexpected
