“It’s just not manly to leave your bro like this, after knowing he can’t do anything about it, you know?” Kirishima blabbers some kind of bullshit excuse, and the worst part is that it looks like he’s totally convinced of it. “It’s just a— handjob,” he stumbles over the word, the weight of what he’s
