Sips and Sjin had an argument about Sjin's flirty ways in the last Sipsco factory which lead to a break up. Both Sips and Sjin were heartbroken and went there separate ways; Sjin turned to Nilesy for help and Sips kept to himself. Sjin and Nilesy's relationship was a very close one, and Nilesy, having had a crush on Sjin for months, thought Sjin might have liked him back. Sjin was, after all, ridiculously flirty with Nilesy and they did do things (kiss, cuddle) they wouldn't do with just anyone. However, Sjin was still in love with Sips and, over time, they reconciled, deciding to rebuild the factory. Things are a bit weird because they're technically not together, but they both flirt and act like they're in a relationship. They're both still in love with each other but too proud to apologize, but both think they're doing fine and are happy with how things are.
Nilesy, however, was heartbroken when he learnt about the new factory because he was scared for Sjin - he knew how controlling Sips could be. He doesn't know what to do and might ask Lomadia for help, she has always there for him.
