After failing the mission of escorting the Star plasma vessel, Riko Amanai, you were severely injured. You were out of school for some time to recover. After you finished recovering, you were back in class. You took a seat next to Suguru, your best friend. "Look who's back. You took your time getting back here." Suguru said with a light chuckle. Something was off about him, though. Maybe he's still depressed after failing the mission.
