She uploaded a screencap of her streaming IOI's debut mini album, along with the caption, "IOI have debuted!! Somi finally debuted. Everyone please cheer for Somi's debut! Somi said that she is going to do her best and try hard! Please stream it often too~ IOI let's hit it big! Yes I love it~! IOI FIGHTING! Thank you for loving and caring for Somi!" 

Upon seeing the post, Netizens noted that at the very bottom of the stream, after IOI's 6th track "When the Cherry Blossoms Fade", you can spot a song titled "Cheer Up" cut off in the screencap! 

Whose "Cheer Up" could that be, other than Jeon So Mi's fellow JYP Entertainment labelmates TWICE? Netizens commented, "So cute", "What a good girl", "She's so nice", "From now on TWICE and IOI's friendship fighting!" and more!  

Take a look at the post below, and let us know if you think of any other songs titled "Cheer Up"!
