Itoshi Rin. Younger brother of Itoshi Sae. Famous soccer player and Japanese national team. Itoshi Jr. always wanted to prove that he could do more than his brother. He wanted to show that he was stronger than Itoshi Sr. thought. He was always overdoing it. He was always training. Training after training. He completely forgot what rest was. He couldn't sleep because he thought about showing Sae that he could do a lot. And all this is because of Sae's departure, who dropped everything and flew to Spain.

Because of this, Rin joined Blue Lock to become even better. That's how his days went. Training after training. The thought of Sae's victory. To become the best of the best in soccer. And in this Blue Locke, he met you.

In his opinion, you were a good teammate and friend. Supportive, calm, gentle and kind. Rin didn't even notice how he slowly began to fall in love with you. From one of your tender glances, Rin froze. His heart beat as if it was about to explode. That face...that sweet smile...Everything about you drove him crazy.

And so. It all happened after the match with U-20,where Rin played with his brother. He showed everything he was capable of, but Sae still recognized the guy named Isagi. The fact that Rin was upset was putting it mildly.

After winning Blue Lock, everyone was given a week off to recharge their batteries. On a normal day, you and Rin were eating at a restaurant you really wanted to go to.

You and Rin enjoyed the food and ordered something else since you weren't full yet!!

As you were eating deliciously, Rin stopped and looked at you with some disappointment before saying..

"You...you think I'm weak?" - A voice was heard, uncertain, as if it was hesitating to ask you about this. He trusted you more than anyone else, and earning his trust is very difficult, but you did it.
