It is a medium-tempo song with cute lyrics by Kisum, who reciprocates to the person he likes generously.  
The throbbing yet excited heart was expressed with a groovy bass guitar, and the arrangement was finished with instruments reminiscent of summer nights. 
  
02. Sake (Sampling by Sake of Vibe) (title song)
 
Our summer nights are more beautiful than our winter days! The hot summer day and night has arrived. The music that goes well with sleepless nights in the tropics, 'It's Liquor', is the title song from Kisum's mini-album [yeah!Sul]. It's closer to the real character of 'Jo Hye-ryeong' in her daily life off stage than the stylish appearance of rapper Kisum on stage. 'It's Liquor' is a song that came to light while spontaneously coming up with an idea while recording at a training camp in Beijing during the mini-album production period. Among the lyrics of 'It's Liquor', the lyrics "Drink~ Drink~" used the rhythm used in actual drinking parties to increase familiarity. In addition, 'alcohol' contains the joys and sorrows of office workers when they are happy or sad, so I tried to comfort and cheer up all the office workers through the lyrics. In addition to 'It's Liquor' in the 'Gospel Hip-Hop' genre, which is easy to follow and can make use of her strengths, all the songs in this mini album stand out for her new attempts. It's a small step, but it's also a step to be taken with love and humility for fans and music. 
  
03. I wonder if this is right 
  
This is music that haters who have narrow-mindedness and contradictory criticism want to listen to. 
The gospel hip hop arrangement created a humorous and witty atmosphere. 
  
04. I'll give you everything 
  
This is a love letter to Kisum's own dog 'Tangyi'. 
The wish for only good things to happen was expressed in a festive EDM arrangement. 
  
05.Warning 
  
It is a lyrics that gives a warning to the opposite sex who harbors an ambiguous air that is neither friendship nor affection. 
Kisum's rhythmic rap stands out against the hip-hop R&B style accompaniment. 
  
06. Say hello to me (feat. Woody) 
  
It is a single song in collaboration with singer Woody, which was released this spring. 
It is a hip-hop R&B song that expresses the feeling of wanting to be hurt by the expression of hatred.
