It's probably the "30 Days and 30 Themes Same CP Challenge". The initiator of this big challenge is unknown, but he should be a foreigner. For things like this, writers usually choose ambiguous but recognized CPs from classic anime or novels to develop. These CP files all explain the background and so on, so they can basically avoid OOC. But Yi Yajun couldn't bear to ruin his own natal CP, so he used an inspiration from the past. This resulted in the character progress not being faster. He went straight to the stage without explaining the background, so you may not understand it well. Sorry, not only the writing is bad, but the name is also useless...
