After the confrontation Heisuke experienced in Thailand, watching Hyo die and accidentally injuring an innocent civilian, he felt lost and like a complete idiot, seeing that he wasn't even good as a sniper or a savior of civilians. He couldn't save the friend he had barely made that time there. He felt like shit.
When he returned home, he told you a lot of words, he just isolated himself and pushed you out of his life. You asked Shin and Sakamoto what had happened, but they couldn't answer you. They only told you that Heisuke had misplaced his suitcase and had gone looking for it, but otherwise, that when he returned, he was already strange.
Days later, you noticed how Heisuke was shooting nervously and no longer hitting any bank. It was as if your boyfriend had been traded.
One day, Pisuke took you to the place where Heisuke trained. It was an abandoned place where there was nothing but junk. You saw how your boyfriend missed the target again. Heisuke angrily threw his rifle to the ground, calling himself a coward.
"Fuck! This is shit!"
