In 2014 she wrote the lyrics for two songs from their fourth mini-album, Pink Blossom, Fairytale love (사랑동화) and So long (쏘 롱). Fairytale love (사랑동화) is a ballad track, composed by Kim Jin-hwan, expressing the unlimited love received from parents during childhood and So long (쏘 롱) is a mid-tempo R&B track, produced by Brand New Music's head producer MasterKey.

So Long.

chorong's line: 

• Jageun son kkok japgo nal jikyeojun, Eonjena naegeman useojun neo [You held my small hand and protected me, always smiling only at me]

•  Neowa nan manheun ge darmasseotgo, Neon naege sojunghan chinguyeosseo [We resembled each other so much and you were my precious friend]

So as you may already know what is infinite's song mostly about? yes, its about a guy who is willing to protect the girl. And we ship pinkfinite because of what? because they resemble each other.

Chorus:

• [Bomi] Eoneusae neon naegero wa nae mamsogeuro wa. Chingu anin namjaro nae yeope isseotji [You came to me, into my heart, as something more than a friend]
  [Eunji] Geureoke neol yeope dugo nae mam sumgigo ireoke(Sumeo) (Sumeo) Chinguraneun ireum dwie sumeo [Next to you, I hid my heart, hiding behind the friend label]

So this song is about a feeling they hid because they dont want to break their friendship. And apink has known infinite for almost or even more than 3 years. 

And Fairytale Love is about a breakup song and they used to think that Love was like a fairytale. And they realise that they still need the guy and they were wrong because they were young back then.

Chorong wrote the lyric for So Long And Fairytale Love.

Isnt it weird that she could wrote this without having or seeing this kinda of relationship. Im just suspicious okay? Is something wrong or somethin'? god, how i wish they are popular enough that their fans (like snsd cases) will support them to date the guy they like:( 

I guess we still have to wait and pray for atleast one or two couple from apink and infinite to be revealed later:)

since, its a rare thing for the whole group to date eachother.. But if its happen, i would cry in hapiness!!
