I read the raw even I can't understand a thing from it but when the twins were attacked in ch 25, arien try to protect arjen by hugging him & let herself receive the impact...it's actually really heartwarming to know that arien always act as an older sister to arjin even she's actually the youngest between them...
It's over? Oh, I'm gonna miss the short story of them when wowo & douding still a kids... they are so cute..
