CLASS:y released two new singles, “Tick Tick Boom” and “ZEALOUS,” within seconds of each other on October 26, 2022, just five months after their debut. “Day” means being a student and living a relatively normal life, whereas “night” relates to being an artist and feeling the pressures of recording, filming, and promotions rather than worrying about exams. The two singles complement each other as they truly are Day&Night.

“Tick Tick Boom” was written and composed by Yoowon Oh, Ryan, Anders Nilsen, Kristin Carpenter, Askjell Soltrand, and Simen Thunes Hope. The music video shows the truth behind being a rookie group while trying to balance studies and being an idol. The members share their struggles about leaving their family and friends behind and that they no longer have the advice or support they need to get them through their busy schedules. They look back on these memories fondly, yet their anxiousness shows they’ll be interrupted—and they are when a phone notification snaps them out of their daze. The music video also shows the pressure of having to look perfect for promotions and that it’s sometimes too much to handle. They later reference their experience of being in a survival show when the votes rise as they compete against each other in another scene.

“ZEALOUS” was written and composed by Yoowon Oh, Ryan, Hanif “Hitamnic” Sabzevari, and Dennis “DeKo” Kordnejad. CLASS:y or “ZEALOUS?” You decide. The music sounds like gugak (국악), traditional Korean music, composed using a taepyeongso (태평소), a type of trumpet. The music video starts with several news broadcasts talking about big store sales as customers battle each other. The members' confidence doesn’t waver at this news, as they know they’ll be the ones to reach the item first. But is this due to their zealousness or their style? The lyrics suggest that shoppers should be in awe over their appearance, strength, and attitude, and are paralyzed as CLASS:y make their way through the aisles. However, the music video shows them destroying public property outside of a supermarket as if to say “we don’t need this cart because our hands are strong enough to carry any weight.” Perhaps it’s not just the weight of shopping they’re talking about, but also the life of an idol. But we have to wonder, is it the fashion that matters or the chance to show off? Either way, their second life as an idol definitely seems more fun in this aspect as night tops day.
