The fan actually says “Can you say ‘I love B.A.P.’?” which prompts Sungyeol’s reaction. The question gets repeated and Sungyeol ignores it to focus on the other fans.
It’s one thing to bring up another group, but it’s a whole other level of rude to treat him like he’s some sort of parrot. He’s a person, not some English-speaking novelty. He obviously understands and speaks the language with some degree of fluency so why not try and hold a conversation with him, rather than try get him to say things for your fancams. I’m not surprised he looked offended, honestly.
This took longer than needed, glad its finished though. I have yet to play this game. I am saddened by this aspect but i’ve been watching walkthroughs of the game and I still get the feels for this series’ great expansive story.
