Debate

 "Tha ... tha ...!" Ryushin screeched. He stretched out his hands towards Jeje.

 "Thank God ... thank God, Ryushin is fine. Papa promises to take better care of Ryushin after this. Sorry, My Baby?" said Jeje, softly. He was still holding the baby warm.

 "Tha ... ta ...." Ryushin answered again. That was all he could say at the age of 6 months, even though Jia and Jeje didn't even know what it meant.

 "Let's go home, Je!" take Jia after.

 "Help Jeje carry Ryushin like earlier, OK, Sis?" Jeje asked.

 Without being asked, Jia was willing to put the finger cloth on her brother's shoulder to carry Ryushin. Jia can't be riding a motorbike while carrying Ryushin, right? Moreover, telling Jeje to shake them. It's possible that Jia's motorbike, which has not been paid off, was put into the sewer by her younger brother, because Jeje couldn't bring his previous motorbike.
