Hawaii arc (Spoiler)

Inseop and Wooyeon went to Hawaii for a shoot. Inseop saw Wooyeon's ID and noticed that his birthday was coming up. He asked one of the staff to drive him to downtown to buy a cake for Wooyeon. When Wooyeon saw Inseop disappeared, he started searching for him because he thought he ran away. He saw a scene where an Asian person was stabbed and the person was being transported on a stretcher. Wooyeon thought it was Inseop. He ran over and got blood all over him, but it turned out it was not Inseop. He then looked for Inseop in the city and at the airport. After 3 hours of searching for Inseop, he returned to his hotel room. He saw Inseop and got really angry. He threw the cake and attempted to rape Inseop. Wooyeon stopped after seeing Inseop crying and scared. Wooyeon started apologizing, saying he would never do it again with tears. Then he confessed, but he didn't know if it was love because he has ASD. This is when they started talking about Wooyeon's ASD and his past. Inseop said that it was okay if their feelings weren't the same, as long as they were similar, and they started dating.

After their Hawaii trip, things were normal for a while. Until Inseop met a crazy fan who stabbed him. Inseop drove over to pick up Wooyeon while he was bleeding. He bled all over the driver's seat when he arrived. Inseop was brought to the hospital by Wooyeon. Then Inseop's family from America came to visit him. After his life-threatening experience, Inseop went back to America. Inseop wrote letters to Wooyeon and then Wooyeon came to visit him in America, and they spent a lot of time together. They also talked about Jennie and how Wooyeon never read Jennie's letters. The girls who used to bully Jennie came over and apologized to Inseop.

Wooyeon returned to Korea, and Inseop followed him. Inseop was still working for him, and Wooyeon promised to propose to Inseop if he won an award for acting. One day Youngmo threatened Inseop and beat him up. Inseop was hospitalized, and Wooyeon took care of him. However, he was treating him very coldly. Inseop got kicked out of his apartment, and Wooyeon brought him to a villa. It was revealed that Wooyeon already received the award, and he kept it a secret because he was planning on giving the villa to Inseop, as well as transferring all his assets to Inseop in the form of legal inheritance. So Inseop would forever stay with him for the rest of his life. He didn't think he could live without Inseop and find another love. Inseop met Youngmo at the award ceremony before it started. Youngmo told Inseop that this actress and Wooyeon were together and would probably get married. Inseop confronted Wooyeon, and Wooyeon said that these were normal scandals. Inseop was heartbroken and left the award ceremony. Inseop was contacted by his real estate agent to meet an apartment owner. Inseop moved into his new place after leaving the award ceremony. Wooyeon found Inseop, and they got into an argument. Wooyeon got so upset he crushed a cellphone in his hand. The glass cut into Wooyeon's hands, and blood spilled all over the floor. Inseop panicked and told Wooyeon he needed to go to the hospital. Inseop got short of breath and fainted.

When Inseop woke up, Wooyeon apologized for what he said and told Wooyeon the truth about Youngmo. Then Inseop became depressed and developed gastritis. Wooyeon talked with Chairman Kim and confessed how he couldn't live without Inseop. But he also didn't want to put Inseop in danger. He urged Kim to buy Inseop a plane ticket to America. Chairman Kim visited Inseop and gave him a plane ticket for America. Inseop began packing for America. Then he realized why Wooyeon was acting so cold because that night when Inseop called Wooyeon, Wooyeon was actually at Inseop's home. So this whole time, Wooyeon thought Inseop was cheating on him.

Inseop found Wooyeon sitting by the water (it was raining), and they had a conversation. Wooyeon expressed his frustrations with their relationship and told him to die, but Inseop told him he loved him, and they spent the night together.
