[All] I like the love letter song because it's sweet and spring-like

It is a song full of excitement depicting the beginning of love, and it is a song that well expresses the refreshing emotions of the hero.

It's a song that brings back the innocent feelings of love.

It's a song that makes you laugh for no reason when you listen to it, and the lyrics and melody tickle your ears.

I like it even more because it's a bright song that reminds me of Lim Young-woong's smile.

It also has a warm charm that reminds you of your first love.
