Hui Wan is a feisty high school girl. Kim Ram U is a transfer student to Eunsung High School. On April Fools' Day, their classmates decide to swap names for a day, and Ram U and Hui Wan swap their names. After swapping their names, Hui Wan has her best day. She feels like swapping names with Ram U brings her luck, so she wants to keep swapping their names.

Ram U died four years ago. And four years later, he goes to Hui Wan as a grim reaper and tells her that she will die in a week. Hui Wan can't believe what she sees and hears and refuses to talk to Ram U. As Hui Wan is lethargic and wants to do nothing before she dies, Ram U suggests that Hui Wan complete his bucket list together.

Ram U and Hui Wan share many memories. Hoping to make her feel better and encourage her to stop isolating herself from the outside world, Ram U drags Hui Wan to her college. However, Hui Wan feels unbothered and wants to push Ram U away.

Hui Wan cries and tells Ram U that she couldn't forgive herself and that the past memories alone give her enough pain. She wants to quit completing the bucket list with Ram U. Meanwhile, Hui Wan goes to see Hong Seok. However, Hong Seok doesn't seem happy to see her.

Hui Wan really wants to see Jeong Suk and tells her the truth that Ram U's death was her fault, and that it was not because of Jeong Suk. However, Ram U thinks Hui Wan should move on and stop feeling guilty.

Although she wastes most of her week, Hui Wan still has one more day to say goodbye to the world. She prepares gifts for Hui Ju and her father. With Ram U, Hui Wan wants to go on a typical, predictable date with him. Meanwhile, Hui Wan keeps getting calls from Yeong Hyeon.
