I’ve added the guide for the soulmate route to the main post as it requires a few specific choices (if not using SKIP). Though right now, I still don’t know why this route might be mixing with the neutral path in Chapter 4.
Edit: I’ve made a workaround for the bug that was mixing routes, so it shouldn’t happen anymore.
Though I didn’t locate the troublesome part yet. 
Rue my beloved
well, that was a fun ride.
Although I couldn’t for the life of me trigger any romance interaction with a female Sieun as a female character. Are there any specific choices that must be made in order to move forward with the romance? I’ve read that something is supposed to happen in chap 2, but never got anything. 
edit: oh, somehow I also got the skip from the Acropolis to the risotto without knowing what happens in between while being on the soulmate route with both female MC and Prue. Not sure if that’s supposed to happen (played the whole thing from the start) or if that can be of any help. 
It’s definitely helpful! Now I know my workaround doesn’t fix that particular bug I still haven’t tracked down
So for now, the safest way to do the soulmate part in the update is by skipping straight to chapter 4.
Thanks for the report!
edit: Just to make sure I understand: did you skip the entire Ernest meeting at Acropolis (no conversation with him at all), and went straight from waking up-messages to the risotto-label part?
Did you go on the fishing trip with Mark earlier? If yes, how did it end for you?
edit2: So, tracking down that one bug has led me to the following conclusions:
I’ve missed some possible outcomes of the fishing trip that make you “fall” through the code to the part with the label, bypassing the soulmate variable checks. (I’ve made a workaround for that)
You’re possibly not on the soulmate route, because if you were, the MC would receive messages from Prue/Rue at the beginning of the chapter and call them to get details about the meeting.
The soulmate route can only be triggered by reaching that one specific ending of the motel scene.
Of course I may be mistaken. 
If Seb ends up in the hospital, the MC will have the option to go to a bar with Sieun during the second visit (Chapter 2). From Chapter 3 onward, the romance is in full swing. There’s a restaurant date available, as well as a date at Sieun’s apartment.
If the player chooses Sieun as their RO instead of Seb, the romance continues on Seb’s route — or rather, it builds on their already established relationship.
It’s possible that one of the stats is locked. To make sure you unlock the romance, you either need to go to the bar or have a relationship score of 60 or higher. You can raise that score by volunteering to be the hostage instead of Sieun during the “shitty job.”
sorry the workaround’s not exactly working as intended! Maybe it’s the universe telling the MC to gtfo and go live in the woods instead?
But yeah, I skipped the whole thing, and did not go to the fishing trip (Mark did not invite my MC ) . Basically I also went from “Stepping out, you head straight toward the conference room, entering without knocking.” to “Getting back home, you spend some time preparing a huge portion of risotto” just as the post above.
edit looks like we answered at the same time 
. I think I am on the soulmate route though! I do get to see Prue’s messages and phone call during the stuffed nose incident.
Ah, Seb never ended in the hospital, so this would explain that. I suspected it had something to do with switching the route or stay on track - should have tried that. I’ll mess up next time to see what happens! Looking forward to get to know a little more about both Sieun and Seb. Thanks for the tip!
Thanks for the additional info! I’ve finally tracked down the bug and fixed it. 
As for the soulmate path, I thought you had exactly the same bug as @Sel_Lee (jumping straight to the meeting with the label without any previous mention of it in the text). But if your MC called Prue, then the route is working fine.
Awesome!
What exactly is the soulmate path? Is it different from the regular Prue/Rue path?
I briefly skimmed through the most recent comments, so if this was previously covered I apologize for rehashing it. Has Mark’s route now been released yet? Personally I’m not interested in Seb’s route, and I have already played through Sieun’s route and loved it. I have played through it maybe twice now trying to advance Mark’s route with no luck on getting his storyline to progress.
I personally don’t like Marks route. It is odd. I normally like daddy routes but he doesn’t show any interest in anything I say. I went for the soulmate route and it is so nice. I am the red flag girlfriend in that route. 
I usually don’t go that route, but I thought it would be interesting to see how the dynamic of MC’s crime family would change and play out as their romance progressed.
We’re a mobster and we’re not walking around strapped?
So? You can have all the healing you want, the point of having a weapon to be able to deal with threats to you or others without having to resort to just your fists. Right now, we’d have to steal a weapon to be able to do literally anything offensive. If we had offensive powers, I wouldn’t bring this up, but right now, we have purely defensive powers.
Also, don’t we still feel pain? We had a headache in the beginning of the demo. So just because you can heal, your character would let someone shoot them? …Why? You can just…not.
And the Father trusting us or not doesn’t matter. He has us to his dirty work. If he expected any degree of genuine results, he would have let us carry one. If he wanted, he could just have us be patted down and disarmed every time we come home. He’s rich.
The story has no explanation for this at all. It’s just a fair bit of an oversight, it doesn’t ruin anything.
No? During the ‘shitty-ride’ job, MC has a choice to go armed and can use that gun.
MC doesn’t walk around unarmed or defenseless by default.
Yes, you can use guns in the game. I didn’t say you couldn’t.
Not from what I played.
