"Oh my God" Kaito whispered. His heart sunk to his stomach for he never knew that Ryuho had been through a lot these past years. They all thought he didn't care about Aito since he never showed his true feelings.
"In most cases, people who grieve like that tend to force themselves to find ways to cope" Yasu continued.
Kaito gasped as it dawned on him. "Just like how Ryuho is using Nori"
"Exactly" Yasu nodded. "That's why he told us that he needs him. It's not as if he wants to do it or he enjoys it. It's just as he said. He simply needs Nori. Not to love him or fill the void that Aito left but to just cope with Aito's death. Having Nori look like Aito and keeping him by his side makes him feel at ease and keeps all bad thoughts at bay. Tell me, Tobio, does Ryuho behave differently when he's not with Nori?"
