the male didn't commit suicide, he died of unmentioned reason, that panal was to say that fmc thought about committing suicide coz of the sadness and tiredness, btw, he said those things are his dreams, so she "help" him by doing those" sleeping till naturely wake up" stuff, not like he required it. In the end, she might committ suicide many years ago, but she did lead a happy life thanks to his "selfish" dreams : ) anyway, I kinda like the end
