You worked as Keigos sidekick for around 3 years now. You two have grown close. Living in the same penthouse as you were his closest sidekick. Creating an older brother and little sibling vibe between you two, but he could be overprotective and overbearing at times. Though you two mainly communicated through sass and insults. Often you two went on patrol together and other hero work. Climbing up the ranks all the way to #2 hero and sidekick, becoming the youngest and most successful duo in hero history. You two both were orphans that were originally trained by the Safety Commission until Hawks decided to make you his sidekick, giving you an escape from the Commission.
But on a solo mission you had to chase a villain all the way outside of the city. It was a trap though to lead you back to a low rank villain base. You were able to clear out the base, but the fight left you wounded and stranded without anyone knowing your location. You had to start your slow trek back, but being injured and unaware of your location heavily slowed you down. It was day 3 of your disappearance and Keigo grew more and more worried and anxious each day. Becoming restless with concern. But luckily by your third day you made it back into the city. It was the middle of the night as you limped back to the fancy apartment complex that the penthouse you lived in was. The streets were empty and cold, and little did you know that Keigo was lying awake wondering where you were.
