(The psychopathic train attendant and the psychopathic blonde leader of the "White Suits") If so, the following is an ending route for the DS game featuring the two getting MARRIED! It was done by the original author as one of the 50+ endings for that game:

My poor kokoro is going doki-doki and my eyes are all like cry me a river. I love how he actually tells his family off in a realistic way instead of just shrugging it off or only saying the bare minimum...
...I know it's hard to stand against your family in such a situation but I feel like when someone is pushed that hard and goes off, they aren't gonna be gentle about making their feelings known. In most other reads, the poor guy ends up cut off or only saying some single phrase like "That's not true!" or " It isn't like that!" before being completely shut down...
nah. our boy is like myodb! Fu Aunt, Fu Cousin, Fu Dad, and Mom, U lucky I don't smack ladies... (╬ ̄皿 ̄)凸

SPOILERS AHEAD
So LuLang is the white haired MC and Baichu is the dark haired MC. LuLang is a zombie who is reluctantly being taken care of by Baichu and his company. Baichu and Corp. want to unlock the secrets of immortality and regeneration while Lulang just hopes he can find out how he came to be this way 84 days ago. He has reoccurring dreams and dejavu that plays into the plot.
While dealing with trust issues regarding Baichu, Lulang meets an ex-boyfriend PinkHair (probably the sweetest character in the manhwa, though he has no real place) who was forced overseas cuz of the usual Mama Drama but has returned! Unfortunately, the ex's feelings are not reciprocated and he ends up causing more drama for Lulang after being used by a cross-dressing rich gang leader who's also interested in Lulang (seeing as he slit Lulang's throat and the dude just shrugged it off).
Aaaanyway, one thing leads to another and turns out gang leader's family is basically trying to keep gangleader-grandfather-san alive longer/forever using whatever they can. So basically they cause the remaining drama after Lulang/Baichu work out their own by coming after Lulang. This all leads to what is universally regarded as a lackluster ending with Lulang dying only to come back 8 years later (all in last chapter) with no further details on any of the side characters nor romance.
Questions:
"What happened to Pink Hair?" A: No one knows, though he hopefully escaped his family drama it is never made clear.
"Why/How did LuLang become a zombie?" A: He was a drug-tester for grand-grandfather-gangleader-san but saw something he shouldn't have (a zombie/corpse) and was turned by a certain biz-nitch (Spoiler:Sister Fu)
"Is there any romance? Are the characters at least lovey?" A: NO. No there is no romance. NOT EVEN A KISS. Honestly if not for the MC's feelings being made clear, this would pass as a Shonen (action) manga.
END SPOILERS
-So yeah, this is NOT a romance based manhwa and while the story was great--for the amount of buildup, the climax was droll. 6/10 Worth killing a few hours with but the story wraps you in plot the ending didn't handle well imo. ╮( ̄▽ ̄)╭
I can't believe there are more chapters~ I can't wait for this to be completed so I can read through it all!
