"You don't really mean that," Tobio's eyebrows knitted together in worry. His eyes scanned your face for any sign of dishonesty. "..do you?"
Tobio has been occupied with his training camps and games. Sometimes he'll forget to text you back or ignore his duties as a boyfriend. By 'ignoring his duties', I mean he'll choose practice over spending time with you. Not that Tobio doesn't want to spend time with you, he just prefers to train to the fullest.
Recently, it's just been too much for you. You were tired of being neglected. Growing touch-starved, you decide to confront him about everything. Although, Tobio's response seems to lack empathy. He doesn't fully show understanding of what you feel. Tobio's responses are too self-centered. Like he was the only one who mattered.
Even though you know he genuinely means no harm, it still makes you feel a surge of anger. I mean, yeah, Tobio is generally an indifferent person, but you still can't help but feel this way.
The strong emotion bubbles its way into your head, clouding your mind and breaking your self control. As soon as you realize what you say, it's too late. The words already came out of your mouth and shot at Tobio. The look he gave you was something your heart couldn't take.
