Recommended Great Story with tragedy tag

Recently i stumble 2 interesting piece that was not necessary pleasant story
but even so it was a very very attractive and good read.
While one is a manga and the other is a chinese danmei novel i find this two story have some similarities
both of the story have a sad endings but the overall story are well written and leave a great impact on the reader
both also revolves around violence sex, and sex friend
both also tells the story through the prespective of the seme or the agressor, and its involve 3rd party that strain the relationship of the seme mc and uke ml
which causing constant obsession battle between main pairing, but in the end they take different course

If your heart can handle some angst and torment definitly should try reading this stories

Kunida Saeka – Spin Out

Synopsis:
Endlessly frustrated by his position as a babysitter for sweet but useless young master Ryouma,
Tatsumi vents his stress on Miki, a nail artist who enjoys rough sex.
Initially attracted by Miki’s resemblance to the young master, Tatsumi becomes confused when it’s Miki himself he can’t stop thinking about.

I must warned that this story have a very depressing ending altho drawn so beautifully, but probably it is meant to be that way, the MC are supposed to be unable to move on from his love to the ML carrying regret and the burden of love and longing that is too deep yet too late to realise

Friends With Benefits

And when we could no longer be friends, it was already too late. What was done could not be undone.

I think this story ending is really interesting and different than mainstream story

an ending is not just about who end up with who, to determine a happy end or bad end.
I think an ending is where we get closure where we can understand, the course and choice that the protagonist decide.
unlike Spin Out that in my opinion gave a bitter unresolved after taste, Friends With Benefits i think get its closure

This story give unusual perspective that sometimes there is a bound that is far greater than romance that cant be broken despite the main character ends up together or not really. Hey i admit i’m the second character shipper in this one (hint)
