Just as the name suggests, this is a drama about 'falling in love' because the love in this drama is never resolved. The story is about three protagonists who are childhood friends: two boys and one girl. The boys are like the polar opposite, one is super popular and is always rejecting girls (misunderstood as a psychopath) while the other is timider and always is getting rejected by the girls he asks out. The girl, Shi Won, seems to have a crush on Pa Rang (timid guy) while Shi Eon (popular) seems to have a crush on the girl. As the story starts, Pa Rang seems to be super reliant on his friends especially Shi Won, Shi Eon, and Kim Geon to take away his fears of being alone because he has separation anxiety. However, as the start progress more and more, we can also see that Shi Won and Shi Eon are reliant on Pa Rang to get rid of their loneliness as well but don't seem to realize it because Pa Rang acts [or shown) as the 'glue' of the group to his anxiety. Even though Pa Rang asks Shi Won out, he ends up getting rejected due to Shi Won thinking that he is just asking her out as he did with other girls (no true feeling). Although Pa Rang and Shi Won had a feeling for one another since childhood, they end up 'failing in love' because they don't really express it to each other. It's the opposite with Shi Eon who finally expresses his feeling to Shi Won after 10 years but he also fails in love because Shi Won doesn't accept his feeling even though she seems to have a feeling for him as well. In the end, Si Won realized that she didn't have to take care of Kang Parang all the time because Kang Parang could take care of himself and Shi Eon shows more of nice sides. The drama also ends with Pa Rang building up the courage to be more independent but he still has his fear while Shi Won and Shi Eon go to their classes. The main point of this drama is self-realization because the theme of love is never resolved in this drama as it ends without anyone ending with each other but they do come to a realization about themselves.
