Life is ever-delightful — and ever-challenging — for a group of friends in their twilight years as they rediscover themselves through love and family.

Right after Ryu Sun-jae, a top star, ends his life, Im Sol, his top fan, somehow ends up at a time when they were in high school and tries to protect him. A fantasy romance unfolds where people who missed each other in time finally meet.

The guest is king — but so is the host! Yu Jae-seok opens his first B&B, where he runs things his way and treats guests to his signature games.
