In the book apparently Mi and Sila had sex haha, but neither the original or the new version give mention to that (actually with Bie, Mi was always suggesting it as a joke but it never happened). In my opinion though, and from subtly reading between the lines, I think perhaps they've had some intimacy before in this version (not a relationship), but they at least know each other well and are close. More as friends than anything, but it's up to us what we make of how they were before this.
In terms of Sila's love life, he's the owner of a night club so he'd had definitely slept with women before (otherwise he'd be a virgin with Kwan and I don't think that's the case lol). You know, I even thought of the possibility with the woman Oil (who was beaten up by Sawit and lost her baby, ended up killing herself) that he had had sex with, as Sila seemed to care a lot about her and often brought her up as a reason to his revenge. This is completely a guess though.
And either way, even if Sila has a long list of sexual partners, it's clear he's never been in love or loved any woman ... Like the way he has with Min.
Their romance is just pure goals.
The book has that? That they really did it? Wow. So that explains why she goes into a corner to answer his call, it's special. She's very attractive & probably lots admirers (Sawit can't take his eyes off her) but with Sila he even knows she's prone to gambling & warns her off it so they must be real close. Seems the sleeping together (if that happened) is a mutual thing that isn't serious & without permanent expectations on either side. The other thing is she's a good enough friend to not take advantage of him - when he said he's giving her 2 Million, she refused to take it for free. But to repay in giving Sawit the run around she was happy enough to do it.
Oil now. Err, I don't think Sila had anything like that with her. (Yayyyy) He gives a brotherly take on this. The panics of Waen, Bak, Mam over her in that episode is like she's family, only they seem to rely on Sila to decide on situations like those. And he did went sort of responsible & angry like a big brother would. I have this impression that the Devil Club/Casino is a closed up world where Mam & Sila protects their people from prejudice, derisiveness, danger from society. Who enjoys vice (gambling/ women/drinking) would love them whereas society shuns & looks down at them. (I hated the parts where Sida & Wan persistently calls Mam low class & dirty). When it comes to handling the public over "their people" Sila & Mam would front the honours. Oil came across as a young employee of the Club & fragile so the superiors (Mam, Sila & gang) cared a lot for her.
Yeah, I'm beginning to get that - he's had lots of women. The way the girls stood up & were fawning when he first appeared at the club, he must have had his pick one time or another. Ahh don't talk about Kwan! What he gave her that one night I hope was one of his most lame performances hahahhahahah (it must be because him a dog or not she never went to hanker to him for more)
What's good is he's already sowed his wild oats while not even expecting to find the right girl. (He told her he's never given his heart away) Unconsciously he also became a better man in every sense to offer the ultimate of a perfect person, worthy of the lovely Min. So he was pretty shocked when she went teary-eyed as she called him "P'Tor", because this is one aspect of his past which he never considered. But suddenly she's there, rocking his world.
