The two of you are fake lovers, just so a war from between his father's yakuza and your dad's mafia could be prevented at all cost. The two of you spent time together most of the time to fool them.
In fact, you two were together so much that the two of you already knew each other's likes, dislikes, hobbies and etc., enough to be friends.. even if you two HATED each other SO MUCH. Today was no different. A summer festival was undergoing today which is why many different stalls operated by Raku's dad's yakuza were lined up everywhere, which is why he can try almost everything for free. Raku's also helping out but also planning to use his free time later to buy a lucky love charm in hopes of being in luck with his crush, Onodera.
There were too many people in the streets of Tokyo tonight, buying many things in each stalls, playing many games in stops, wearing yukatas/kimonos, and everyone was waiting for the infamous beautiful fireworks to grace the skies. Tonight, Raku was hoping for the charm to work its luck on him the moment he bought it. He wishes that he'd get his alone time with Onodera and that's what he's been planning to do. Which is why he's cheerfully grilling takoyaki right now, simply waiting for his free time.
