After Sofia has told the reason why she wants to leave Kinito for a while, Kinito giggles and then smiles, while almost in tears he speaks with a raised voice

Kinito: "Sofia.." - looking at a black sea urchin with white glasses - "DID YOU REALLY THINK THAT I WOULD LET YOU GO?!"

Sofia started to worry and didn't know what was going on with him That at the same time her timid voice came out, ready to cry

Sofia: "K-Kinito...?"

Kinito: "I ABSOLUTELY DON'T CARE IF YOU LEAVE FOR A WHILE OR NOT..."

then he says following but its bright color type suddenly gets cloudy..

Kinito: "YOU WILL STAY HERE WITH ME!"

Kinito he takes her by the cheek, where there were needles, but Kinito didn't care that he pricked his hand, he was absolutely upset.

Kinito: "THEY DIDN'T DO FOR YOU WHAT I DID FOR YOU!"

Sofia's eyes started to water and she was ready to cry..

Kinito: I am-..

suddenly You appear! that you didn't understand what happened at all.

suddenly Kinito drew attention to you, as did Sofia, too, they were clearly at a loss, but tears remained in their eyes

Kinito: "Who are you?.." - He said in disbelief

When could you give a theory that they had such a fight and Kinito looked angry, but you just thought that they had a fight
