Spoiler-free. The whole manga feels like a bad trip. It's just weird, chaotic and... well, bad. Weird elements really makes you think stuff like "I wouldn't want to be this mangaka's neighbor, god knows what's in their head", it may sound intriguing for some, but it's the creepy eery kind of weird with a good pinch of cringe. And about the 'shounen ai' tag... it's like, this manga tries to be josei, slice of life, comedy, shounen ai, all at once... but fails. 'Shounen ai' is what loosely stitches this bloody mess together... or, like I said, tries to.
Art is somewhat interesting in the first volume I think... closer to the end it becomes worse, interestingly enough.
Characters... *sighs* let's not go there (there is nowhere to go).
Enjoyment... after the final chapter you end up feeling guilty for the hate crime against yourself, does it sound enjoyable to anyone. Well sometiimes there is a funny moment, but usually it's a trash kinda fun which adds to the severity of the hate crime previously mentioned.
Anyways I wouldn't recommend wasting your time on this weird garbage.
