'Knowing Brothers' saw a touching moment between Oh My Girl's Seunghee and Arin, as they confronted their friendship in front of the other members.

On the latest episode, Oh My Girl's Seunghee and Arin were designated as 'two members that are most uncomfortable/awkward with each other when alone.' Seunghee set the stage for a lighthearted interaction when she shared an "embarrassing" incident during a livestream on her birthday, when she found out that Arin had forgotten to save her new phone number. While Arin, in her defense, explained that she wasn't aware of the change, other members later acknowledged that Seunghee and Arin "truly" displayed some awkwardness when left alone.

The pivotal moment came when Seunghee and Arin stepped forward to hold each other's hands and express their gratitude for one another. Seunghee, being the older member, sincerely thanked Arin for her unwavering dedication "since joining the group at such a young age." Overwhelmed with emotions, Seunghee's tears began to flow, provoking a similar response from Arin.

Although it was Arin's turn to respond, the younger member could not hold back her tears and simply gave Seunghee a hug.
