woojin was cheating on taehwan, not minho. they might be each others first (doomed) loves, but they were never in a monogamous relationship.
AGAIN
Woojin didn't cheat on Minho, he got close to the caretaker but that's it. He even asked him for help to get Minho a gift. Minho was insecure and didn't trust Woojin so he ended up betraying and treating mc like shit.
I think woojon ex is just so hurt about the fact the he was cheating on him while he was away, his feelings is valid but booy the way you got you're revenge on woojin is so veery wrong. Well anyway hope to see on the next chapter how was Minho after 3 years. What an interesting story!
