Ignore the description, it literally doesn't even happen. The set up is that these two have loved each other for years, but ended up in a fake marriage to help their families, so each keeps lying to the other about why they do things for each other and continue the misunderstanding.
I recognize that I'm rating this really highly because I'm a sucker for these tropes but still. I really got sucked in and enjoyed this. Great if you love mutual pining. They're both SO IN LOVE but for a variety of reasons they both keep messing it up and/or believing it's all fake and could never happen, so. If you love those tropes, go for it.
