The Art and story are definitely worth it, but yes it is rushed and the ending will not be satisfying for others.
At the very beginning you will definitely get attach especially when you see the MC's misery and desperation. So it make sense the ending will be disappointing and lacking but I say it's worth it to read once not really something you'll come back to read.
We'll see more or less when the side stories is out. ¯_(ツ)_/¯
It's great.
You can always say or promise that you'll focus on studying/work over and over again but in the end as a person with feelings you cannot beat love you'll become a fool no matter what.
That part is what felt so real for me. Anyways I just wanted tell my perspective so I came back to re-read this. (⌒▽⌒)
