Riku rejected a call from Keiki when he met the friend at the park
Because in the last chapter Keiki was calling Riku and Riku ignored his call, hence he got worried.
Either rejected or ignored dont recall
I thought Riku was the one calling Keiki? But why was he asking Riku *why didn't u answer your phone* instead??? (〜￣△￣)〜 I'm too distracted by this to question anything else...
