try watching a walk through! also make your you monitor the affection bar thingy, for example, when picking your fav movies, do horror and pick slasher or ghosts..I cant rlly do a full walk through so yea, I'd watch a gameplay of it
try to get the affection bar high! I was struggling with this too but you just need to flirt with him, pick horror and slasher genre, and be friendly or basically just try to relate to him or anything actually related i guess!!
