after being diagnosed with his disease and the later death of his boyfriend/fiance/husband/whatever, shiro becomes obsessed with the desire to eliminate death, excelling at miskatonic university and generally liked except that he gets very indignant about death and anyones attempt to just dismiss it or whatever
keith is some young pluck to comes to the school and meets shiro and becomes fascinated with him and his perspective on life and death and ends up just... fucking following him into his stupid plans because hes just so awestruck with shiro
