The last episode named "This Goodbye isn't Forever" melted the hearts of its audience as everything has been put into pieces.

Yoon Songhee (Kim Sun-young) spent some time with Soo-bin and gave her trust back to her daughter. Yoo Soobin asked for a favor and gave comfort, "... I don't care about my dad; I just want to live well alone and I've done my best so far. So, don't worry about others."

Lee Yeonwoo became embarrassed with Jun-woo as she lost the income to upgrade their restaurant. She worked for part-time jobs to gain their money back and re-open their restaurant, but to no avail, this has given Jun-woo an idea to stick with her mom, far away from his academy and helped for their business. But then, Yeonwoo insisted to focus on his exam.

Ma Hwiyoung (Kang Ki-young) was depicted for the tampering of his grades at the end and decided to drop out of school to know himself better. He stepped down his pride and apologized to Jun-woo for all he had done, and he is willing to payback for all the mishaps that had happened.

Summer vacation soon began, and this has given the chance for the students of Cheonbong High School to study and get ready for their future. The couple never had a chance to meet each other ever since their summer and Choi Jun-woo decided to meet Yoon Songhee and convinced her to go out one last time with Soobin as he will leave the academy to help his mother for their business. Soobin's mother further then felt Junwoo's sincerity and allowed them to meet.

Kim Jimin (Ho Young-Ji) finally passed a job interview after the help she got from Oh Hankyeol (Kang Ki-young). "Thank you for waiting and supporting me. I'll make a formal proposal now. I'll go out with me." They had happy endings as well.

As it progresses, the couple had the chance to look back at the places they had memories with. Jun-woo admitted that he will be leaving soon. Soobin knew about it and felt the pain Jun-woo was holding for a while. He advised her, "I'm asking, but I hope you don't come. I don't want to show you leaving."

As the day had come, Soobin focused on her studies and followed Junwoo's advice. She saw Junwoo's bike with the paintings he made to recall all their memories. Soobin ran after and gave her last goodbye to Jun-woo.
