This one is really interesting and compelling. I’m not much for tragedy, but this is on my list of exceptions. Fair warning, it can be straight up depressing, and current events are not being kind to those dealing with depression, so ymmv. I’d add it to my library but probably wouldn’t read it for a while.
I would also very like "Usotsuki" to be published, foremost because the character's dialogues are intersting and the protagonist's lies, to the reader and other characters, are, at least for me, both entertaining and unique.
