ok this is the page 3 of the manga
This is China's first Appearance, China was Looking for Maniolas because he wants to show him something (or somebody) to him which I didn't mentioned in this page. But When China Came Maniolas was a bit grumpy because he disturbed his family time which made china a bit angry which Maniolas thinks as little bit OA (Over Acting)

Sorry If I failed at this You can Kill me for that ^^
