Tsukishima and Kageyama

Kageyama Tobio was convinced that this relationship was completely normal.

After class, he would meet her, they would walk together, talk for hours, and although he wasn't exactly good at expressing his feelings, he was happy by her side. To Kageyama, she was his girlfriend. There was no reason to suspect otherwise.

What Kageyama didn't know was that she was also dating Tsukishima Kei.

And Tsukishima knew it.

The first time she noticed Kageyama with her, she didn't say anything. She simply watched from afar as they walked together after practice.

"So it was him..." he murmured to himself.

He wasn't exactly surprised. More like a mixture of annoyance and curiosity. He was bothered that she'd decided to keep it from him, but he also wanted to understand how far she intended to go. If he confronted her immediately, she'd probably deny everything or choose Kageyama to avoid complications. Tsukishima had no intention of giving her such an easy way out.

From then on, he began to notice small details.

The messages Kageyama received during training. The times he disappeared after class. The way he smiled when he looked at his phone.

Tsukishima knew exactly who was behind those messages.

The curious thing was that Kageyama had no idea that Tsukishima was also receiving messages from her.

At first, Tsukishima wondered why he continued to tolerate the situation. He didn't trust her, and he certainly didn't enjoy spending his time with someone who lied so easily. However, there was something about the way she secretly sought him out that fueled his curiosity. He wanted to know if she did it out of affection, for fun, or simply because she enjoyed having them both under her control.

Furthermore, as long as Kageyama remained ignorant, Tsukishima retained an advantage. He could observe them, compare their reactions, and wait for the moment the lie began.
