Yua is a teacher at a school, she is also of puberty age so her mother always forces her to go on dates. Even though she didn't like it, she could only agree so that her mother wouldn't bother her anymore. Suddenly she met Yuki sitting alone crying. She approached to ask, but he just gently dodged and left. The following days, she saw that Yuki was quieter than usual. At lunch time, he still sat quietly in class, so Yua continued to come and ask him questions. It turned out that Yuki's parents had just divorced. Even though she knew that their relationship was not good and was mentally prepared, Yuki still could not avoid being hurt. Yuki didn't have money today, so Yua invited him to eat with her. Of course she couldn't openly buy food for Yuki. They both bought two meals and then went into an empty room to eat and confide in each other. From that moment on, the two always had lunch together, talked and joked. But one day, the person Yua's mother arranged to go on a blind date with her came to her house to pick her up. Yuki also accidentally saw her getting into another man's car. Knowing that he was not as good as others and had no chance, Yuki decided to give up and the two of them should not have lunch together anymore. Yua tried to hold on to Yuki, and for a second she couldn't control herself and kissed him. Knowing what she just did was not good, Yua left confused. But since then Yua has learned her true feelings, the person she loves is Yuki, her student. Even though she knew this was wrong, she couldn't lie to herself. The next day, when everyone had returned, she called Yuki to the empty room and confessed her feelings to him. In response to Yua, Yuki also confessed that he liked her but their relationship was a forbidden relationship. Yua didn't care, she only knew that she liked Yuki, she wanted to give everything she had to him, wanted to become one with the person she loved. Although the future path was very difficult, there were many challenges that forced the two of them to choose whether to give up or continue. But in the end, because of love, they accept the first path with all difficulties and throw everything away to be together...
