In the latest episode of "When the Weather is Fine," Im Eun Seob (Seo Kang Joon) was unconscious in a dark forest after he was hit by a tree branch. He woke up before midnight and started to walk towards the cabin. Mok Hae Won (Park Min Young) searched for him around the area, and she met Eun Seob while her face and her dress were covered in mud. She ran and reached out to touch Eun Seob's face to check if he was still burning with fever, but he pulled her hands and walked away.
They both went inside the cabin for a rest. Eun Seob told Hae Won her to stop coming to the forest or in the cabin. He advised her that next time, she should not bother to look for him even if he is sick. Hae Won felt pain in her heart when she heard Eun Seob's words. It was then the third time that he rejected all her efforts to get closer to him. When they started to walk back to the village, both never said a word. Hae Won slowly walked behind while Eun Seob ahead followed the trail.
The following morning, Hae Won realized her body was not well. She did not eat her breakfast nor report to work in the bookstore. At the entrance, she stared at Eun Seob without any word as they parted ways. Eun Seob went to the market with his mother. His mother cried and scolded him for going to the forest with his condition. She forbade Eun Seob to go to the forest again, and he asked forgiveness and comforted her mother.
The special book club gathered as scheduled, which is held once a week. Members shared packed snacks and started to read their favorite story for the night. Everyone enjoyed the poems and shared thoughts about finding happiness in life. Hae Won mentioned that happiness should be within yourself and not to find somewhere else.
The club members ended their meeting. Hae Won took her jacket and walked home. Eun Seob ran after her and offered the medicine pack. Hae Won did not accept it and continued to walk. He grabbed her hand and once again begged her to take the medicine. Hae Won expressed her sadness why he never said anything about how he feels about her. She asked for answers if he likes her or not, but Eun Seob silently asked forgiveness and Hae Won walked back home with a heavy heart. As soon as Hae Won reached her room, she cried hard thinking of Eun Seob's reaction.
In another scene, Hwi (Eun-Seob's sister) needed to get the book that her brother borrowed. He left it in the forest cabin. Meanwhile, Hae Won tried her best not to show her disappointments and decided to continue working. She met Eun Seob's mother inside the bookstore and asked her to go with Eun Seob going to the forest. Eun Seob told her not to mind her mother and he can go alone. Hae Won disagreed and told Eun Seob not to overthink about the past.
While walking to the forest, both put an ample distance between them and did not smile nor look at each other. Eun Seob found the book and told Hae Won they will go back to the village right away, but she he told him to go home first because she wanted to look around. Eun Seob looked at her and followed her to the lake. Hae Won stood in silence looking at the sight. Then, she started sharing her thoughts about her feelings. She fell in love with his warm and caring treatment every time they are together. Mistaken for his kind actions, she felt really sad.
Eun Seob was standing beside her, looks at her face closely. Hae Won was about to walk away but Eun Seob suddenly grabbed her hand. They looked at each other and Eun Seob slowly moved closer to kiss her. Hae Won was surprised yet felt Eun Seob's tender lips and closed her eyes.
