Mountain always enjoyed showing people that he cared, but was often too shy to say it with words. So, when he first figured that he likes you, the ghoul did his best to show you in his own way.

He started to leave little trinkets, sticky notes with kind words or your favorite sweets in places where you would find them.

You had no clue who had gifted you all of these until you once went back into your room at the ministry. Finding Mountain who had just placed fresh flowers, of course your favorite, in the vase on your nightstand.
