WIZ*ONEs call them Tom & Jerry because they usually joke with each other most of the time, especially during the COLOR*IZ era. Examples of these are times during IZ*ONE CHU, like Yena teaching Sakura her strange ways in Korean culture and Sakura giving Yena onigiri with pickled apricots. Their MBTI functions are flipped. Yena is part of ENFP line with MadMakz, Sakura is the only one that's INFP.
