Kyosuke (Kimura Keito) holds the last letter sent by Saachi (Nakayama Nakayama) in his hand. The edges of the envelope have been worn white, but he still can't muster the courage to open it.Whenever it was late at night, Kyousuke's heart was filled with endless regret and guilt. He was afraid that the words in the letter would become pain that he could not face.

After Murasaki (Rei Ishikawa) learned that her husband had made something like a settlement letter, she experienced a fierce inner struggle.She knew that this might be an opportunity to redeem Kyousuke. She was willing to pay the settlement money on Kyousuke's behalf, but was rejected by Kyousuke. Purano felt unprecedented frustration and powerlessness.She looked at Kyousuke's back, and an indescribable complex emotion surged in her heart, including sympathy for him and anger at her own powerlessness.

After Kaname (Michi Sakurada) was revealed by Murasaki that he had been spying on her, a trace of panic flashed in his eyes.To start telling his past, with a tremor in his voice, he confessed that the reason why he did this was because of the persistence and love for Murasaki deep in his heart.Zi Nai was also shocked. She did not expect that there was such an emotional entanglement behind Kaname's behavior.

Saachi, on the other hand, has been in a trance after his sad separation from Kyousuke.Her heart was filled with fear for the future and nostalgia for the past.After realizing that she could no longer sink like this, Zaozhi decided to complete something of great significance to her while her memory was still clear.She hopes to use this action to bring an end to this relationship, and at the same time, it is also a kind of relief for herself.
