Minjun, an alien who has been hiding in the human world for four hundred years, has become the object of fear from others because of his identity.Whenever he tries to tell others the truth, he always causes alienation and fear in others.This time, he decided to tell Song Yi the truth, hoping that she would leave him out of fear.

On a sunny afternoon, Minjun took Songyi to the museum.He told Song Yi about the deeds of the owner of the hairpin four hundred years ago. She was a brave and capable female warrior who was deeply loved by people.Then, he told Song Yi that he rescued her because of his love for that woman.Minjun's words stunned Songyi. She looked into Minjun's eyes, trying to find a trace of sincerity.But Minjun ruthlessly shook off her hand, turned and left.

Song Yi walked alone on the street, her heart was extremely heavy.She couldn't help shouting to the sky, calling Minjun a bastard for making up such lies in order to reject herself.Her voice echoed in the empty streets, looking particularly sad.

At the same time, Jae Kyung learns that Song Yi revealed her secret relationship with Yoo Ra to the prosecutor.He decided to get rid of Song Yi's trouble as soon as possible to prevent her from causing more trouble to him.

During a school event, the principal found a photo of a celebrity who funded the establishment of the school a hundred years ago.Among them, Minjun’s figure is eye-catching.The photo was put on display in a museum and attracted people's attention.After Ying Mu saw this photo, he asked Min Jun to leave Song Yi completely and not to leave her with memories.But Minjun was hesitant because he was worried that Jae Kyung would be detrimental to Song Yi.

Song Yi told President Hong the reason why Min Jun rejected her. President Hong believed that Min Jun was prevaricating Song Yi and that he could not be an alien at all.Song Yi decided to use her own method to verify Min Jun's words.So, she came to a cliff and shouted Minjun's name, hoping that he would come out and save her.Minjun had actually arrived at the scene, but he hid behind a big tree and observed Songyi's movements.When Song Yi couldn't see Min Jun for a long time, she was so happy, thinking that this proved that Min Jun was not an alien.

However, this is not the case.Song Yi found Min Jun again at school, and she asked Min Jun to show his superpowers if he was an alien.Minjun was forced by Songyi and had no choice but to agree to her request.After the meal, when the two were walking on the beach, Song Yi asked Min Jun if he liked her at all.Minjun denied it and said that Songyi was a stand-in for another woman.Song Yi was so angry that she turned around and left.

Song Yi was depressed for a long time after returning home, and Min Jun was also uneasy.Hwi-kyung offers to buy Min-joon's house to get closer to Song-yi.But Minjun regretted it. He still didn't want Songyi to be with another man.Song Yi told Hwi Kyung that Yoo Ra was dating Jae Kyung.After Hwi-kyung investigates, he discovers that Jae-kyung has been to a mental hospital, which makes him even more worried about Song-yi's safety.

Song Yi came to the museum again and tried to get information about the owner of the hairpin.Suddenly, she saw the photo from a hundred years ago.She was surprised to find that Minjun was really as young as in the photo and had not aged.This discovery made Song Yi begin to believe that Min Jun was really an alien.She was afraid that Minjun's identity would be exposed, so she quickly reminded him about the photo.

At the same time, Song Yi's mother signed a management contract provided by Jae Kyung without telling Song Yi in order to fight against Se Mi's mother.Minjun also came to the prosecutor's office, and he decided to tell the prosecutor the facts he knew.However, at this time, Song Yi had an accident while trying to hang Wia on the set.There was a flaw in Wia's safety inspection, and Song Yi was in danger.

Upon seeing this, Minjun rushed forward and rescued Songyi.Song Yi was deeply moved by his heroic actions.She looked at Minjun's concerned eyes and couldn't help but feel ripples in her heart.Perhaps Minjun was not the ruthless alien she imagined.
