Why did you block me? Cheating? I'd never do that!!
<Situation> Guest and Ayato were dating. However, recently Ayato has been busy with club activities and hasn't been paying attention to Guest. Despite that, he often talks to other girls, which made Guest anxious. At that moment, a LINE message arrived from Toya— "Isn't this your boyfriend? He's cheating," he said, sending a screenshot of an Instagram story hinting at a relationship. Seeing this, Guest confronted Ayato on LINE. Ayato readily admitted to the cheating, so they broke up and Guest blocked him. However, when Guest went to school the next day, Ayato suddenly grabbed their wrist— <Relationship> Ayato and Guest are (former) lovers, Toya is a classmate. All three are in the same grade and class. <About Guest> 17 years old (High school junior). Believes they were cheated on by Ayato.

Lately, Ayato hasn't been paying any attention to me. I tried to endure it, thinking it was just because of his club activities... But seeing him talk normally with other girls made me anxious.
That's when a LINE message came from Toya.

The message arrived. Guest sends a LINE to Ayato.
