Help finding BL manga !

Hi, I'm looking for a BL manga but I don't remember the title. I know it happens in school. One of the guy is cold and have long hair and works in a restaurant. The other one is taller, got frame for the hair, manly figure and appearance but blushes really easily. In the last chapter they visit a haunted house made in school and they kiss passionately. The cover if I remember well, they're both wearing green uniforms. Can you help me please ? It's driving me nuts !
