EXO's Xiumin, Baekhyun, and Chanyeol made a heartening appearance on LE SSERAFIM's youngest member, Eunchae's series titled "Eunchae’s Star Diary," which was aired on July 20. The episode was characterized by a relaxed and playful ambience, as the senior EXO members offered their guidance and shared their wisdom with their junior, Eunchae.

As the session commenced, Baekhyun acknowledged that Eunchae might be anxious given the unconventional 3-to-1 recording setup, a departure from the usual one-on-one interaction. The EXO members attempted to ease her tension by engaging in a casual conversation about LE SSERAFIM's concert. The revelation that Eunchae is only 16 years old left them astonished, prompting lighthearted jokes about Xiumin's age being twice that of Eunchae's.

They offered her reassurance, affirming that they were there to support her and that her stress levels would likely diminish in the subsequent episode featuring Kai. Their sunbae guidance set the tone for a constructive and enjoyable episode.

Following this, Chanyeol commended LE SSERAFIM's "Bloom". Eunchae then asked for advice on how her band could have longevity exceeding a decade. To this, Baekhyun responded that perseverance and a professional mindset are crucial for long-term success in the industry.

Chanyeol added that it's beneficial to maintain close relationships with band members. Baekhyun echoed this sentiment, emphasizing that it's more rewarding to be close friends with fellow band members than to focus on building relationships with other celebrities.

Xiumin, in concurrence, believed that this principle is the secret behind EXO's enduring camaraderie and mutual understanding. Due to this bond, EXO members have been able to avoid internal conflicts, further solidifying their unity.

As Eunchae became more comfortable, she shifted the conversation to lighter topics, including whether the EXO members had any regrets, if they ever search their names online, and their experiences with impromptu dance challenges in music show hallways.

Baekhyun and Xiumin expressed their desire to have more interactions with EXO's fandom, known as EXOLs. Chanyeol, recalling their challenge requests, admitted that even the mere thought of them set his heart racing.

At the end, they recorded the "Cream Soda" challenge. In addition Eunchae explained she was nervous but she thanked the EXO members for creating a comfortable and fun atmosphere and stated EXO is the best.
