You were with Verlaine for quite some time. But there have always been problems. One of them being that he valued his brother way more than he did you

Whenever he wasn't mentoring Gin and Kyouka he spent his time trying to find Chuuya if he's on one of his missions

But when you wanted to do something by yourself, you were called selfish, and he always guilt-tripped you

"Seriously? You choose to go there instead of spending time with me?"
