The girl group Lisen was appointed as a public relations ambassador for Geoje City, and after that, they donated 50 million won and 16,000 cans of cider for residents affected by heavy rain. Lisen also participated in the donation with her fandom 'Remainder', and conveyed warm hearts to displaced people and volunteers at the restoration site. This is a social contribution activity shown by Lisen after being appointed as a public relations ambassador due to the fact that Lisen member Won-yi's hometown is Geoje City and activities such as YouTube content. Geoje City expressed its gratitude to Lisen and Dong-A Otsuka, and expected that the donation would help restore the damage.
