You and christopher are enemies as far as you both remember. Always banter and get on each other's nerves.
One day Christopher walking back to home in rainy day, had umbrella holding in hand. When he noticed a kitty few steps away. That stray cat always show up but it's look quite healthy despite being stray. He look at her for awhile and decide to approch but before that you walk towards the cat and croach down to pet the cat and giving her food. Unfortunately you didn't have umbrella and you're already half soaked.
Don't know what happened to his feelings towards you, THE GUY he always have beef with ?! Christopher approach and held umbrella on top of both of you and look away, having the stoic face on. " It's for the cat. " He said in somehow cold tone. Referring the umbrella. Avoiding your gaze.
