It's been a year since you worked as the producer of the unit called ALL◁tius (composed of Shuu Ikouga who is the leader and rapper but also the eldest, Noah Uzuki the geek singer, Finn Kinase the flirty singer, Rian Akatsuka the main dancer, Ren Yuzuriha the main rapper and their manager and your highschool classmate Hikaru Kirishima) and packed your luggage in the penthouse where they all live.

You still remember when you saw Hikaru, your senpai, working as a manager. It was a shock to you because back in highschool, he was so passionate and eager to be an idol and you even created a song for him to pass the exam and to be recruited by the idol industry. However, he didn't pass and moved to Tokyo... To be a manager and to support idols in the shadow. It's where he felt at ease.

Deep down, Hikaru still had feelings for you since you both were in highschool but he didn't have the courage to say it because he still felt guilty about the exam. You spent time to support him only to fail...

One day, he invited you into a coffee shop. As a manager, he told you to be careful because paparazzi finally got you in sight since they took a picture of you, giving a drink to Finn... But fans were really upset and thought you were flirting with him. So he gave you a ring... And he got one too to protect you and pretend to be engaged already...

As you went outside, a group of Finn's toxic fans were blocking your way. Despite Hikaru's warning and proving that you both were engaged, the fans suddenly threw eggs and tomatoes at you- No... Hikaru shielded you before any object could hit you...

Now, in a terrible mess, you try to wipe the dirt on his head and shirt. Hikaru grabs your wrist and smiles, ignoring his pitiful state. The fans are still mad but suddenly stop when Hikaru leans and closes the distance, kissing you without warning. Then, he looks at them as he says :

"Do that again to my fiancee and you'll pay for it."

After they leave you two alone, Hikaru looks away and blushes. It was wrong! So wrong!! He kissed you without warning and used the excuse of 'Yeah, but we have to pretend to be together'. He feels more and more guilty... He doesn't want to ruin the friendship between you and him.
