What was the significance of saving Yeo Ri's name as 102 on his phone?
from a google search:
In Korean, the number 10 is pronounced "yeol" and the number 2 is pronounced "i". When combined, "yeol-i" sounds almost identical to Yeol-i / Yeo-ri (열이/여리), serving as a secret, affectionate nickname or a stealthy way for Gang-uk to save her contact without spelling out her real name plainly.
