After the group took a rest for three days straight in their apartment, they continued to practice the dance choreography they need to perform during their debut. In the meantime, the third teaser of the album, "Always" released on 30th August. It was, even more, shorter than the previous two, just a thirty-second teaser. Since this one was just a melody and slow beat music unlike the other two and only have like 10 seconds of singing and that too, only Sungjun's, it only caused tiny waves on the internet.
While it wasn't able to gather more views than the previous one, "Burn it up" but still, it has a positive response on the internet. Although the netizens were excited to look forward to Jun's profile teaser, a few of them also complained that the company is biased towards Jun, giving him most of the show time in teasers too. But since he is the face of the group, and it is a common thing in the industry, no one cared about such complaints.

As for the audience, they were surprised as they saw the one they were waiting all this time, have the least amount of training period among all but soon all of their worries and disappointment, disappeared the moment video clip of him started.
It's in one of the monthly evaluations; he sang a male version of a song of Lee Hi, without any mic while piano music began to play in the background. They cut the start of the starting part and played the middle 25 seconds, which is the best part of the song, the most vocal part with a very high scale range,
"Someone's breath. That heavy breath.
How can I see through that?
Though I can't understand your breath
It's alright... I'll hold you"
As the teaser is over, thousands of netizens began to comment, "Woah, Sungjun-Oppa's amazing" "that song, damn... Echo, please upload the full version of it" "Sungjun-Hyung, your voice is amazing." "I like Sungjun-Oppa's version better than original" "only 11 months of training period? Where was he, all this time?" "Saranghae, Oppa" "I'm much hyped for their debut" "I realized I just developed a crush on Sungjun-Oppa." "This is his original voice, right? Why did it sound so magical to me?"
Instantly, the teaser hit 100k views just within an hour as it was shared all over SNS. It even got the attention of the idols from Genesis and ZC. Since it was kind of a song that addressed Kpop idols based on the lyrics if one thinks in a different way, most of the rookie idols as well as others, who are working hard to reach the expectations of their higher management, watched the original and then just liked the video without commenting anything.
Meanwhile, as Sparkle group was also watching the video clip for a second time, Yunseo just grabbed Yungja's hand and said, "At this rate, I'm going to develop a crush on your brother, Yungja. What to do." As once again, they started to tease Yungja, which ended up with her closing the video, although no one saw Nayoung's troubled expression as she placed her hand on her chest and thought for a second, "He isn't my type at all. I wonder why my heart is beating so fast. Is it because of his voice?"
Before the wave generated by the video slowing down, on 6th September, just three days away from their debut, YeongCheol released the final teaser of the album featuring the fourth and final song.
It's a 45-second teaser. After the company logo appeared, music just played while they were walking in some kind of room filled with chairs, skateboard, and miscellaneous things, and finally, in the background, everyone sang only one line.
"Boom, boom, boom, boom... Boomerang."
After the teaser over, YeongCheol said, "only three days away from the debut of Unlimited. Our boys will debut at the Samsan World Gymnasium. Tickets will be issued on 8th September. There will be performances of a few more groups. But that will be a surprise. Those who can't get a ticket, fear not. There will be live streaming on YouTube."
Since there was a concert on that day for Sparkle, Yungja apologized that she won't be able to attend it or watch it on the live stream. Then, Jun called his mother and informed her about the news, which made her teared up with happiness as her son, finally about to achieve his dream. After talking with his grandparents, vaguely, Jun disconnected the call.
On 7th September morning, Since the five of them were picked by Pak Taehee, one of the senior executive directors in the agency, who was actually, one of the judges during Jun's scout and his training period before pre-debut. When asked her about it, she just replied, "Well, until your manager gets hired, I will look over your activities. Anyway, get in."
After reaching their agency, they sat in one of the conference rooms, filled with chairs and desks, the place, where usually, formal press conferences are being held. Waiting for a while, they took their seats after the press and the Chairman have arrived. They were asked various questions like how they are feeling to finally debut.
What difficulties they faced while recording and shooting, things like that. But then, all of a sudden, one of the freelance journalists stood up and asked, "my question is here to Han Sungjun. I gathered some interesting things about your personal life. Can I ask it?"
As Chairman looked over him, who sat in the center of the group, Sungjun nodded as he knew this day would also come eventually. The journalist then asked, "The first thing is that is it true that you used to be a trainee at ZC for three years?"
Before Jun get to answer the question, Yeongcheol stood up and said, "I'm sure the other journalists and reporters have important questions about all of them but it's already late. The boys should also need rest and get ready for their debut. Don't worry. We will have one more interview, the next day after the debut, and you can ask him about the questions, alright? Thank you for the understanding."
The press, as well as Jun, was stupefied at his response as they were only talking like 30-45 minutes. Still, as they got the message, they stood up and began to leave.
Later, before they left the company, he asked everyone, not to write anything regarding the link between Sungjun and ZC until their debut, by giving them gifts since controversies before debuting is a bad thing, both for idols as well as for agencies.
