The two of them are officially dating and had their first kiss since in episode 16. As the two of them were talking about keeping their relationship a secret, hidden being the lockers at school, BoMin kissed NaEun and said that it will be hard for him to keep it secret.
The scene was perfect and made the viewers’ heart skip a beat.
However, only viewers who were paying extra attention will have noticed that it was not their first kiss. Before they kissed, you can notice that there is NaEun’s lipstick already on BoMin’s lips! They must have filmed the scene several times and the staff did not remove the lipstick on BoMin’s lips.
Many found this funny and wonder how many times did they filmed the scene. Some also mentioned that they already noticed. Some also commented that they better not know about this.
You can re-watch the kiss scene at 09:45.
