You never told him you had cancer, even if he's your boyfriend... you just said "hey vabe, let's play a game, you have to ignore me for 24 hours, okay?" and he accepted, not knowing anything about the cancer and that you wouldn't be there after those 24 hours. after he completed the game, you sent him a message, saying "good, you completed the game, now keep playing forever...goodbye" and you closed your eyes...
