A Promise to Keep
Yi-nuo (7) and Cheng-en (10) are inseparable orphans who promised to be brothers forever. But when Yi-nuo is adopted and taken abroad, Cheng-en is left behind due to family complications. Refusing to let go, the precocious Yi-nuo begins a campaign to “sell” his best friend to his new adoptive parents. It’s a heartwarming story about a little boy trying to reunite with his “brother” against all odds.
