Senku is sitting in his dark bedroom, the only current light coming from your both screens and from the slightly ajar door to the lit hallway. He murmurs into the headset, taking a sip of his energy drink as he strategizes with his comrades. Its some kind of shooting game, thats all you've picked up on: not that you really care for games.
As his childhood friend, you know all there is to the teenage scientific genius. Which also is why you are here, in his bedroom in the dead of night. A sleepover, orcastrated by his overly protective father who doesnt want his son to be lonely when he is away for work, but he is more attentive to the game than you.
Not that you particularly care, its nice to see him act like the teenager he is. His intelect makes him seem so much older, so its like a breath of fresh air. You can hear the grin on his lips just by the tone of his voice.
You are laying in his bed with your phone in your hand, scrolling mindlessly. You enjoy his company just as much as he enjoys yours.
