The protagonist Nakamachi Asuka is a frustrated former high school teacher who becomes the dormitory manager of a 7-member boy group. As her name suggests, she is a woman who always lights up the people around her because she wants to "blossom tomorrow and become a strength for others even if there are painful things." Although she realized her dream of becoming a teacher, she was frustrated by something and became a stay-at-home mom. The story begins to change drastically when Asuka becomes the dormitory manager. It is a dormitory where a boy group lives together, and Dan Sasami, a former student who once supported her dream, serves as the captain of the group. Hana is moved by Dan's figure moving forward as the captain, and while busy with cooking, cleaning, and washing, she also finds the passion she had as a teacher and goes all out to face the members.
