"You and Songsong have the same blood type. I've read your medical file and the two of you are compatible on many points. Therefore, I'm begging you: please donate your bone marrow to Songsong. Please save her."
An Xiaxia realized what was going on instantly. She was Rh negative — the so-called "panda blood" and a blood type very hard to come by.
So, all that food had been for her bone marrow.
An Xiaxia lowered her head, feeling deceived.
Mr. Song took it as a sign of her reluctance. He then took out a check book from his inside pocket, swiftly wrote down a figure, and put it in An Xiaxia's hand.
An Xiaxia's eyes opened wide. As if the check burned, she drew back her hand immediately.
Mr. Song cleared his throat awkwardly, pondered a moment, and took the check back. He then wrote a new check.
This time, he only signed his name before handing it to An Xiaxia.
"Feel free to write whatever figure you want."
