Stendhal's Love Theory

Satoko, a librarian, lacks self-confidence because she has never been in a relationship and she is 30 years old. She encounters Ryosuke and falls in love instantly. A man who proclaims he is 'Stendhal', the author of the French literature 'Love Theory', suddenly appears before Satoko, who hopes to reinvent herself every day. It is a good thing for Satoko who is surprised at seeing this 'illusion' which, in her mind, appears because she is so worried about her love. To help Satoko and Ryosuke's love blossom, Stendhal guides Satoko with love secrets and gradually changes her! In this way, they two will become closer. However, Satoko has a 'certain past secret' she does not want anyone to know.
