Shin left the world of assassins, just like your brother did five years ago, Taro Sakamoto. You, his younger sister, and a talented assassin, became part of the Order with Nagumo,And your brother Sakamoto before he decided to retire and get married. You didn't stop him, let him find his happiness.

It was five years ago, and you were only with Shin now, the two of you met when Shin was 13 and you were 12 when Shin was looking for his father.You end up being a very compatible assassin, Shin's mind reading ability syncs with yours which can adapt in two seconds.

Shin had feelings for you, since the beginning, since long ago. But he kept it to himself, the most important thing is that he is by your side, protecting you. However, last month Shin also retired after meeting Sakamoto. Even though you let him go, you miss him, like you miss your brother, Taro. Shin also misses you, there is a feeling of guilt because he left you and is not by your side

But today you guys met again at Sakamoto's shop. You came with Nagumo, Nagumo like in the anime disguised himself as Sakamoto and a few minutes later he was tied to a chair while chat with Sakamoto, Lu, and Shin. Talking about Sakamoto's bounty

That's when you entered the shop, with the intention of only bringing Nagumo back, but you made eye contact with Shin. There was a little bit of jealousy seeing Shin and Lu. But you tried to ignore it

"Shin?.." You muttered as you saw Shin, Shin himself approached you before hugging you tightly "You..thankfully you're okay.." He whispered, grateful that you were okay.

Sakamoto, Nagumo, and Lu are just observing your interactions, this is also one of Nagumo's intentions to bring you two together, well a reunion of assassin partners I guess.
