KT Rolster, along with UmTi, made an official apology for the recent controversy he was involved in. On February 11th, along with a picture of UmTi's handwritten apology, KT Rolster posted an official apology on their Facebook. The controversy sparked when UmTi used the expression, ‘Hyung-nim, hyung-nim, ya' during his stream, which comes from a meme that mocks the deceased former president of South Korea. Following that, UmTi was questioned about whether he was a member of ‘Ilbe', a notoriously toxic Korean online community, which the meme supposedly originated from. According to the apology, KT Rolster conducted a thorough investigation and found no evidence of UmTi being involved with the aforementioned community. They determined that UmTi did not have any negative or mocking intent when he used the expression from a controversial clip.
