Dear my Future
Still training in Korea, Hye In was looking forward to the day when she can make her Prism Show debut. Until then, she kept in touch with Mia via video phone, and cheered her on. She had been shown back in Korea, training at night to become a Prism Star. In a flashback, it showed that she had made a promise/challenge with Mia when they were only children. Mia said that she would debut first as a Prism Star, while Hye In said she would. The two still remember this exchange in the present.

Arrival, Wandering and Debut
When she finally does come to Japan, she questions why Prizmmy☆ did not perform a Prism Act for their debut. Hye In is shown to be a hard-worker, along with the other Korean students, with their days consisting of waking, training, eating meals, training, sleeping, and more training.

She soon realized that herself and the other Korean members trained far harder than Prizmmy☆. She wondered why did they not debut and why could they not perform a Prism Act. This puzzled her for quite a while. However, with help from Rizumu, she figured out that the reason they were not as successful as Prizmmy☆ is because their teamwork was lacking. This is why even though their strength was far superior, PURETTY could not win against them in the ping-pong match. Their thought processes were so apart from each other that they could not come together and win.

Although depressed for a bit, she worked very hard everyday with the other members of her team to improve. Finally, and suddenly, they were given the OK to debut, right after Prizmmy☆'s show finished. PURETTY performed their first Prism Show, and Mia was truly happy for her as Hye In performed a Prism Act with the rest of her teammates.
