After Bu Yan's ex shows up, Yuchen starts wondering who the twins' father really is. It's also pretty clear he's starting to get attached to both Bu Yan and her children. In an attempt to get closer to her, Yucehn invites her to his boat, alone. But alone time doesn't last long when his clingy childhood friend shows up with the kids and half the neighborhood for a surprise barbeque. Things seem nice at the get together until Yuchen allows Bu Yan's son to eat some barbeque after being told he's allergic. With that, it looks like all his attempts to get closer to her go right out the window. To make matters worse, the little boy has to go to the hospital the next day. There, Yuchen catches Bu Yan talking with her ex at the hospital, not knowing her son is a patient or that her ex is his doctor, Yuchen assumes the worse and makes a move that crosses the line. All in all, communication is once again key and also something they don't know how to do!
