I fucking LOVE Thrice Married to a Salted Fish.
This is among the best relationships in danmei ever.
Volume 2 starts with angst and grief and all Lu Wancheng's background plans to save Lin Qingyu after his death coming to fruition and the inherent ROMANCE of Lin Qingyu relying on him without realizing he's relying on him to shield him from grave danger and being ECSTATIC when he gets the code that he's alive and slowly realizing he's HERE and for him and Gu Fuzhou is manipulating basically an entire empire to get back to his side and...it's SO GOOD.
And then they're together and they are just gleefully scheming, scheming, scheming, scheming.
Two highly intelligent master manipulators doing everything they can to be together, mainly murder plots, and repeatedly whalloping each other over the head unintentionally with how devoted and in love they are, and at least one party is still in active denial that he's in love.
They're just SO HAPPY together, and part of being happy is working flawlessly together to bring down and murder their enemies without any pretense that they are acting anything but villainously.
They have a hot and heavy sexy-roleplay together (on the bunkbed Lin Qingyu preserved from their first marriage) reenacting how they thought the assassination attempt they arranged might have happened after they were blocked from getting details.
Also, their chemistry and banter is amazing and hilarious.
Gu Fuzhou: Oh no! They're trying to arrange me to marry a woman!
Lin Qingyu: the solution to this is obviously treason and multiple murders.
Gu Fuzhou: SLAY KING! <3 I died once without seeing that guy in his grave before I was, let's not let that happen again. I want him DEAD. XD
Lin Qingyu: yes >:) and if it the assassination fails, I'll solve the problem by remarrying you.
Gu Fuzhou: ......I am suddenly and deeply conflicted about this murder.
The two of them, on their way to a clandestine meeting to check on the results of their attempted murder when they run into a guy that insults them:
Lin Qingyu: what? I learned it from you? I can't curse?
Gu Fuzhou, aghast: I've corrupted you.
