Honestly, it's a huge disappointment. It was hilarious even though it doesnt make sense but they had to have sex ALLL THE FREAKING TIME. If you remove the sex scene, the whole story fits in ten chapers.
Okay maybe a bot more than 10 but it was seriously unnecessary.
Also wtf do you mean "end"??
The uncle part fell into a hole of the scenario?
What was the point on creating him a tragic background and popping a potential boyfriend and drama trauma shit act to just leave it unfinished like this?
And finally
This is just my personal POV, mine and mine alone, ok?
I'm very uncomfortable with the interspecies sex. ML said it himself, "I'm neither a cat nor a human" and you must be around 1yo ffs, be it your real cat age or proportional to human age, it is a huge fail, your appearance and behaviour aren't of a cat this age, it made me feel even weirder.
Yes I'm talking to a fictional character of a story, whatcha gonna do ? ┑( ̄Д  ̄)┍
In the end the whole story was very inconsistent and it makes me sad because it had potential if you just ignore the absolutely totally magically unexplained transformation thing.
