Yumi and Babi's relationship developed from work colleagues into lovers. Yumi resigned because she aspires to be an author and lives in Seoul. Babi got promoted and appointed to an office on Jeju Island. Making both of them have to be in a long-distance relationship. They eventually broke up because an intern, Daeun, has a crush on Babi. Do you think Babi cheats on Yumi with Daeun?
1. Babi found out that Daeun lives nearby and offers her a ride, saying that the public transportation on Jeju Island is uncomfortable. He did tell Yumi that he offered an intern a ride, but he didn't mention that intern was a woman. The two of them go to the office together every day. 
2. Yumi visited Jeju Island and only then did she find out that the intern was a woman. Daeun visited Babi's house to pick up some stuff. Babi continues to address Daeun in a friendly manner, even in front of his girlfriend, Yumi. That's when Yumi found out that Daeun and Babi are close to each other, especially since Daeun lives nearby Babi's house.
3. Babi was on his way to do Yumi a favor, he accidentally met Daeun who looked cold as she was wearing thin clothes. He went to take the outer he had in his car and told Daeun to wear it. 
4. Yumi saw Daeun wearing Babi's jacket. That reminded her of the time Babi lend her his jacket back when they were still work colleagues. She felt anxious and asked Babi when did he start liking her. Babi already had an interest in her way before he lend her his jacket, but he felt like he shouldn't be telling the truth. 
5. There are some thoughts of Daeun attached to Babi's board. One day, Daeun fell clumsily and he helped her as he brushed off her clothes. Daeun still managed to smile brightly even though she got a cut on her chin. Seeing that, Babi thought to himself about how adorable Daeun looked.
6. There was an earthquake in Babi's heart when he found out that Daeun's crush was himself. The earthquake started when she said 'I think I will regret not confessing my feelings to you'.
7. The day after Daeun confessed, Babi secretly drove there to see Daeun from afar and there was another earthquake in his heart.
8. Daeun found out that Babi moved out of his house from Yumi and eventually told her that she confessed to Babi. Before Daeun told her, Yumi had no idea they had this kind of relationship.
9. Yumi asked whether Daeun's confession wavered his heart. Honestly, Babi's heart did waver, but he hesitated to answer it.
Q: Did your heart waver when Daeun confessed to you as she resigned from the office?
A: Yes... Honestly, for a second
Yumi asked for a breakup and Babi told her that the person he loves is Yumi, and that he never wants to break up with her.
Do you think what Babi did could be considered cheating or not?
-He f*cking cheated on Yumi...
-He purposely drove there to see Daeun? I thought he just accidentally saw her... That's cheating...
-If this is not cheating, then what is it?
-I f*cking hate him
-Of course, it's cheating, his heart wavered because of another woman...
-Yumi looked so good with Woong, thoughㅠㅠ I never liked Babi since the very first time I saw him anyway...
-He still had the f*cking audacity to tell Yumi that he loves her after everything he did...
-The fact that he offered Daeun a car ride already pissed me off, but I can tolerate that. However, lending your jacket to another woman is absolutely cheating.
-I don't think it's cheating, but I personally can't be in a relationship with someone like that...
-I don't think it's cheating, but if I ever found out my boyfriend does any of these things, I think I'd lose all of my feelings towards him and break up with him...
-I don't think it's cheating, but I will never trust that kind of person ever again...
-He has a girlfriend and yet he still flirts with another woman. Of course, it's cheating.
-I will never f*cking forgive him. This is absolutely f*cking cheating.
-Even if it's not cheating, I'd lose my feelings and break up with him right away...
