Starting to realize that Mihoyo really loves tragic love stories, which is what this event was about too. There was some unique gameplay involving exploring an abandoned mansion, but none of the text was repeatable there and they summarize the whole story at the end so only the main story is translated. It’s still understandable IMO, but just keep in mind that there was some actual legwork involved LOL.
The rest of the event is just some cute, fluffy run-ins with the guys and enjoying a holiday with them on this island. Happy belated Valentines and Lunar New Year!
