Seven members of the stargazing club swore eternal friendship. Yet at Satomi’s wedding three years later, only Mifuyu, Yuri and Kenta are in sight.
Tomoya tells Mifuyu and Satomi his fears about Yuri. The two women go visit Takeshi, but he sidesteps them. Then Kyoichi sees Yuri being beaten.
Work troubles abound: Kyoichi resents his reassignment, Kenta can’t tell Nanae his family’s business, and Satomi’s husband asks her to quit her job.
Kenta’s cover is blown with Nanae. Takeshi’s paid off his debt and been offered his dream job. He wants to quit the site, but learns Kenta is in debt.
When Kyoichi tells Nanae how Kenta feels, she visits him at home and tells him everything. Meanwhile, a student shows up at Tomoya’s place.
Kyoichi can’t tell Kenta about Nanae’s suicide attempt, but Kenta senses something is wrong. Elsewhere, Satomi commissions a sketch from Tomoya.
Mifuyu learns that Kyoichi and Tomoya fought over her 3 years ago. Yuri is uneasy, sensing bad luck looming for Takeshi as he dives into his new job.
Mifuyu, Tomoya and Kenta look for the missing Satomi. When Kyoichi resigns, his boss tells him his father is still alive. Something worries Takeshi.
Kyoichi’s father wants to meet but he can’t forgive him or his mother for lying. Yuri’s pregnancy comes to light. Meanwhile, Tomoya gets offered work.
Tomoya is asked about his past when he’s interviewed as an exciting new artist, but Noriko brushes off his anger. Mifuyu and Satomi make choices.
Takeshi decides to turn himself in. Mifuyu passes her teacher’s exam, then finds out she’s the unwitting co-creator of Tomoya’s new picture book.
Suspicious about Takeshi’s death, Kyoichi grills Matsubara. A girl interested in the “heart book” asks Mifuyu about the meaning of courage.
