From what I saw the Mac cheated on Juergen (sorry if I spelled that wrong) and when jurgen caught him her was crying and jurgen left him there but when jurgen came back to his house the nyc was already there balling his eyes out
*MC cheated
SPOILERS BELOW
He is, or if not one of them he is working for them, season 1 ends with the reveal
Someone else mentioned the last chapter that maybe Jurgen is part of the Templars and is actually using slight magic on the MC at times (which is why MC against all logic decided to stay with him). This chapter lends the theory credibility imo.
At least, I hope thats the explanation because otherwise I have 0 sympathy for the MC because it would mean he was dumb enough to make the decision to break up with someone but then immediately agree to stay a week with them, even knowing he's distracting and is part of the reason he's doing poorly at his job currently.
I don't think Jurgen is playing this time, the cuffs and his words seem pretty sinister. I don't know whether he's a spy unwilling to lose his source, or just a regular yandere, but either way I like it. I thought their relationship was pretty underwhelming until now cause it was 99% sex, at least now their dynamic has evolved.
