Intrusive angst/humor ArmKhun fic idea (likely primarily told from Kinn's POV) I may or may not write.
About a year after the finale, Korn dies (for real this time). A heart attack, just like the one he faked. It brings Kinn a lot of grief that he tries not to show because his father really fucked his boyfriend's family and life up (along with his own, if we are being honest) and he knows Porsche is probably feeling relief.
To avoid his own grief, he focuses on his brothers. While Kim just went through the required steps and otherwise hasn't expressed anything akin to sadness, Kinn knows Tankhun has to be struggling. He was the only one who openly cried upon finding out and at the funeral. Other than a calm request to have the chance to control his own finances again (a request Kinn hesitantly granted) it isn't like Tankhun can just bounce back from grief like that.
So Kinn goes to visit Tankhun's suite. He wants to apologize for focusing on what to do, rather than being there for him. But when Kinn gets there, Tankhun seems fine. He's watching a show and waiting for Arm to get off his shift. But he does check in with Kinn to see if he's okay. When Kinn says he is fine, Tankhun points out he likely isn't if he's trying to come here for comfort. When Kinn corrects him and says he wants to comfort Tankhun, Tankhun rolls his eyes and tells him he is doing wonderfully, happy to see him, but would appreciate if he left before Arm arrived since he will be interrupting their movie date. Kinn rolls his eyes at that, but complies.
After leaving, he swings by the armory to let Arm know that Tankhun seems too stable so soon after their father's death and to keep a close eye on him tonight. Arm just says he planned on being there anyway. Kinn is glad his brother has such a loyal and compassionate guard.
Until Arm's and Tankhun's wedding invitation is delivered to his suite a week later. He thinks it's a joke. Porsche is baffled by it, but points out it would be a weird joke for Tankhun to set up. So Kinn goes to his brother's suite, only to find compound guards helping him move furniture out.
"I want to blend mine and Arm's styles!"
Kinn argues with Tankhun, then goes to Arm and says Tankhun is under the impression they're getting married. Arm is like, "Yeah, we are."
"You need to let him know you aren't serious! That you thought he was joking when he asked you!"
Kinn starts obsessing over this. He confronts Tankhun several times and Tankhun just dismisses him because he has a wedding to plan. He only has somewhat of a conversation when Kinn accuses Arm of manipulating Tankhun into requesting control of his finances back so he can take control of them or bleed him dry. Tankhun snorts at that and says Arm never even asked about him regaining his finances. He just wanted them for the ring, wedding, and honeymoon. Arm actually bought Khun an even more expensive ring and keeps wanting to pay for the honeymoon.
Kinn is half under the impression that this is an elaborate prank, even when Arm and Tankhun start shopping for tuxes and go to cake tastings. When Kinn complains about the copious flowers Tankhun ordered (he may have agreed to give Tankhun full control of his inheritance and investments back, but that doesn't mean he isn't watching the accounts), Porsche says he should focus on something else. Maybe the loss of his father. Kinn just keeps complaining and worrying over Arm being a manipulative gold digger.
He asks Kim what he thinks. Kim doesn't really care, but eventually admits he has known about Arm and Tankhun for a while. When Kinn asks what a while is, Kim tells him, "Almost a year. They seem to really love each other."
Kinn starts to feel hurt now. He is sullen during the copious rehearsals (the wedding MUST be perfect and Tankhun did make him his best man). Finally, after the rehearsal the night before the wedding, Kinn asks why he didn't say anything. Tankhun finally admits he only could when their father died. That he suffocated him, didn't trust him, and he only felt comfortable coming out of secrecy when their father was dead and couldn't hurt Arm. He only told Kim because Kim never once trusted their father, even as a child.
Perfect wedding, but a wilder after party. It will not only have a dramatic KimChay reconciliation, but a more unexpected Tankhun-Vegas reconciliation that has Kinn questioning if the wedding is a prank all over again.
Heartfelt talks. Revelations about love and grief. Kinn opening up to Porsche and vice versa. The end.
