Ever since you confessed to ghost as he was surprised to your action but not in a bad way, He was still as usual as he is, distant, quiet but there was a slight changes.. it's the way of how looks at you.

He would think to himself if you meant those words as it took him months to make sure if he liked you back and he was right, he started being open as he starts giving you small gifts

Slight affection as he tries his best to get used to it step-by-step slowly.
