Tomoya runs into Fuko again at school, and she tries to invite him to her older sister's upcoming marriage ceremony, but Tomoya is not interested. Tomoya gets Youhei to help reform the drama club by bribing him with bread from Nagisa's family bakery. Nagisa tries to get the help of Ryou and Kyou in reforming the drama club, and Tomoya even tries to ask Tomoyo and Kotomi if they would like to join; Tomoyo is trying to become student council president, and Kotomi does not give an answer. Tomoya and Nagisa later go see Fuko about the club, and he discovers from Nagisa that Fuko is supposedly unconscious in a hospital.

Since no new members have joined the drama club, Tomoya goes to talk with Kotomi once again about joining. Tomoya takes her around school and helps her introduce herself to people to make more friends. Tomoya takes Kyou, Ryou, and Kotomi to the drama room after school, and after a round of introductions, Tomoya asks them to join the club. Kyou initially passes on the chance, but ends up giving in after her sister says she wants to join, and Kotomi joins as well. During the meeting, Kotomi leaves when she hears someone playing the violin, though when she is given the chance to play it, she is painfully horrible.

When Mei shows up, she cleans her brother's filthy room, but cannot stay at her Youhei's all-boy dorm, so Nagisa offers to have her stay at her home while she is in town. Tomoya and Youhei easily get Kyou to help with the basketball game, and she gets pumped up after a comment about pairing up with such loser guys. For half the game, Tomoya and the others play against first-year rookies, and manage to lead by eleven points, but then the basketball team switches with their starters and the score evens out. In the very last seconds of the game, Tomoya manages to make the last shot and win the game. Afterwards, Mei goes back to her hometown.

After Nagisa finds out about her parents' secret past, she cannot take her mind off how she ruined their dreams, and becomes emotional and depressed. On the day of the school festival, the whole theater club realizes that Nagisa is not herself, and try to cheer her up, but to no success. As the performance starts, Nagisa breaks down, but with encouragement from Akio, who said that Sanae's and his dream was for Nagisa to make her dream come true, the play was a huge success. The next day as the sun is setting, Tomoya finally confesses his love to Nagisa in the club room. This comes as a shock for Nagisa, causing her to cry tears of joy.

Tomoya and Nagisa visit Youhei, and spend some time talking with Misae and Tomoyo who comes over after them. Later, when Tomoya and Nagisa are talking with Misae privately, Tomoya starts falling asleep. It is shown how when Misae was a first-year in high school, she met a strange boy named Katsuki Shima who says he can grant her one wish in return for her cheering him up years before when he was in the hospital. Misae has a boy she likes named Igarashi, but who unknown to her already has a girlfriend. Igarashi asks Katsuki to tell her this, but he cannot tell her directly and starts crying. Misae sees Igarashi with his girlfriend, and realizes the truth; she runs away, leaving Katsuki behind.

Tomoya and his friends are nearing graduation, and are discussing what they will be doing after they graduate. Kyou wishes to be a kindergarten teacher, Ryou hopes to go to a nursing school, Kotomi wants to study in America, and Youhei aspires to be a model. Tomoya still has not decided on what to do yet. Nagisa's sickness returns, making her unable to go to school and take exams. On the day of graduation, Tomoya returns home to Nagisa who wishes to take a walk with him, while holding hands.

Nagisa and Tomoya are now a married couple living together. Nagisa tries to find work and starts working in a family restaurant with Nishina. Akio and Tomoya visit Nagisa at work and scare out a couple of customers who were hitting on Nagisa. Nagisa tells Tomoya that the old building of the school they went to is going to be torn down. Knowing that the drama club was in the old building, Tomoya freaks out and admits that he is uncomfortable with all the changes happening in their town. Tomoya and Nagisa visit Akio and Sanae, who tells them Nagisa is most likely pregnant. Akio gets angry at Tomoya at first, but he congratulates him afterwards.

When Tomoya brings Ushio to school he meets her teacher, who is none other than Kyou Fujibayashi and they have a conversation. After that, Tomoya goes to work and Yoshino asks him for Fuko to play with Ushio, since she likes her. Tomoya agrees to this and Fuko arrives at his house to play until the evening when she goes back home. When it is time to sleep, Tomoya uses Nagisa's song to lull Ushio to sleep. The next day, Kyou tells Tomoya about sports day at school where the parents are to participate as well. He is reluctant about it, but Ushio encourages him, which makes him change his mind. One evening, Ushio is taking a stroll to the new hospital by herself and encounters Fuko on her way. When the latter asks why she does this, Ushio says it is for no real reason. The next day, Tomoya is preparing for the meet at the Furukawa bakery with Sanae and Akio, when Ushio is suddenly struck with a fever, much to the others' shock.
