My first watched this romcom was 1st quarter of 2019. I truly amaze the acting of the main lead, Seungho and Soobin are perfect couple i do not feel that it was only an acting scenes when they're looking to each other there was something between them that i cant explain. They really captured the heart and interest of every viewers, loooks like it was natural for them. I love the OST. Story is great although its not happen in real life ( the human allergy) it was the best romcom i ever watched and probably my favorite. Done watching on my 3rd❤
