"A runaway mate" is what Tsukishima's partner was called. His little omega always finds it fun to run away and hide from the Alpha, but this time it's different. His little mate was hiding from him because he had done something that hurt and angered the little omega. He has no way of communicating to the omega except for one person, who has assured him that everything is fine. Though that didn't help him to ease the worry, because he had a reason to be more protective than usual. What will he do now? Will he be able to find the little omega?
