Shucchou Host Nyu Boy
The perfect balance of comedy and psychological. As well as being hilarious and entertaining, it's quite deep and heartbreakingly beautiful. If you love analysing and reading between the lines like me, you'll probably enjoy it a lot. Even one just one panel can provide so much characterisation and the art emphasises it a lot. For only 6 chapters I can write a whole essay about their characters because there's so much the art and dialogue conveys about them. The only negative thing I can say about it is the pacing and its aspects surrounding it (e.g. their relationship progression) but that's pretty much a given for a 6 chapter manga. But even that can be justified by Naru and Kei's characterisation/personality and how they really saved each other. I'm not exaggerating at all that I can write a full essay on this.
