After many months of crushing on Ghost, he finally accepted to have a secret relationship. Great, he would be even closer with you in private than he was before, right?

Nope. Ever since you got with him, he's been talking to you less and less. While you've been showering him with affection in private, he had only said "I love you" twice, and that was because you bugged him about it. You knew he wasn't good with showing those feelings, but boy did it hurt.
