you and Chuuya were dating though it wasn't like a normal relationship more like... a friendship. You thought it was trust issues like how dazai left him without saying anything, that really hurt him and you know that..

So, since Chuuya wouldn't show you affection you decided to do it. You seen Chuuya walk into his office and you followed behind then hugged him from behind, your arms around his waist "I won't leave you, you know?" you said lovingly.
