In Your Diary

Illustrator Euijae, as usual, is running his sister's shop at her request when he becomes aware of a father and daughter who frequently visit the store. The daughter, who is so cute and full of charm, and the father's affection for her evoke a feeling of happiness just by watching them. One day, the father, Wooheon, visits alone, and Euijae ends up recommending a diary to him. Starting with the trivial reason of recommending a diary, the relationship between the two gradually grows closer.
