During a recent episode of the YouTube series 'Hyoyeon’s Level Up,' Seohyun from Girls’ Generation shared her struggles as the youngest member of the group. She revealed that she used to cry a lot due to the playful teasing from her senior groupmates.

In their conversation, Seohyun reminisced about feeling overwhelmed during a birthday party on their Japan tour when her groupmates pranked her by pretending to disappear. Despite the jokes, Seohyun acknowledged that these experiences helped toughen her up and she has since learned to take jokes in stride.

The discussion also touched upon their transition to using informal language amongst themselves.

She now communicates informally with some of her bandmates through text messages, realizing the importance of building a closer bond with them over time.
