BL Series with Sad Endings

Main couple did continue to go together but many that didn't deserve to, died

*Bromance* (with mega strong chemistry and undeniable feelings)

The novel has a different ending, but based on the show, the MC had to wait literal decades till he was able to be reunited with his partner

Boston and Nick, one of the 3 main couples, did not end up together. Now don't get me wrong, I'm not really disappointed in Nick's choice; would've liked whatever he picked.

Could say that it's more of a gay series rather than BL but the MC ended up alone and without the one he wanted.

Although S2 confirmed, you know how that always seems to turn out and thus ended with them parted

Specifically with KimPorchay's story

Wen Kexing dies, leaving Zhou Zishu alone (Not counting the epilogue)

Krailert and Naran's story specifically

Got separated and no S2

Added bc RamKing's story did not get properly wrapped up and TharaFrong's relationship didn't develop well enough to get romantic 

Leon and Pobphab, the second lead couple, went on separate paths. Even in the special episode, teased us but still no happy ending for them.

Dika and Chadok's story 

Although the reincarnated versions of them did get together, still adding it as Intouch and Korn themselves didn't have a happy ending

I'm convincing myself that this isn't canon

MC has to arrest and put the love interest in jail ?

Although the 2 at the end get together, the 2 guys don't since one died.

Has a open ending but the dance scene really sticks to me when thinking of the ending to this.

Kirino Makoto chooses to hide his sexuality and ends up fulfilling the heteronormative family ideal

One of the MC gets really toxic, making death be the most merciful option for both leads

Thunphob and Phleng both die, only reuniting in death

DomeVee's love story : Right person, Wrong time

More of an open ending for Jaab and Jen

Because one is an angel, it's only in death that the two leads get reunited and be together (but even that is left open-ended)

Did end up together, just in the afterlife, though they did have to wait until the other died to be reunited

As a result of Perth's and Saint's managers' situation, Saint did not play the role of Pete in the second season; making the couple be broken up for adjustments

So everyone dies...

Wouldn't call it a BL but Way and Kim do have a sad ending as they are separated by death

I get why they wanted to make a second season and why Hyun Jun couldn't join, but I would've preferred it they just let the story end with the first season as the second season essentially leaving Yeon Woo without Yoo Han or Se Hyun

Depends on how you want to interpret it but seeing as how in the end, Yong Ju doesn't get real closure on the matter, I would say that it still ended in an upsetting manner

Would depend on what pairing you hoped would end up together, specifically between the first 2 main leads that were introduced

You can say that it was a happy ending as they still got to be together or a sad one because both died, up to you

S2 never came but also Nant ends up being dead

Don't remember the specifics, but not happy I at least do remember

Very open ending (I think?)

The ending was a bit confusing but ended up putting it on here since the main couple did get to be together in a way, but one forgets their memories together so...
