"You Came From The Stars" Kim Soo-hyeon-I confesses truth to Jeon Ji-yeon

Do Min-joon (Kim Soo-hyeon-I) prepared to say goodbye to Cheon Song-I (Jeon Ji-yeon) as he had to return to his planet.

Jang Yeong-mok (Kim Chang-wan) was worried how Do Min-joon kept being exposed to danger because of her and told him to clear things quickly even for her sake.

Do Min-joon met Lee Jae-kyeong (Sin Seong-rok) who was after Cheon Song-I's life and told him not to touch her as he would leave with everything.

Do Min-joon took her to the museum and showed her a hair accessory from 400 years ago, then he explained that the owner of the accessory resembled her. Cheon Song-I asked, "How do you know someone from 400 years ago?" He then told her that he was an alien who that came to earth 400 years ago from space.

She didn't believe him and was trying to leave when Do Min-joon broke the glass around the display with his superpower. Furthermore, he asked her, "I thought you said you didn't care what kind of a person I am? I am like this. Does it matter now?"

In the following epilogue, Do Min-joon asked himself, "How does it feel leaving earth and cried in sorrow".
