What appealing to me is that the                                            chemistry between them is intriguing.                                                  Although they tried to disguise themselves                                            that they didn’t know their exes and                                                    wanted to use a fresh way to get along                                                with others, like they were totally strangers; however, some of them failed to do it. The girl, Bohyun, was the first one who couldn’t help but crying out loud and finally collapsed behind the scene of her ex because she couldn’t completely forget him. They had a conversation afterwards, and she realized that he wanted to try to go forward and get to know new friends, which really hurt her and made her heartbroken. This couple is the most distressing and torturing to the audience.
