Shu was shouting at you, not being able to control himself anymore. You age regressed, and trusted your best friend by telling him about that.You were very wrong, thinking that he would easily agree to be your caregiver, or at least take care of you until you find someone else.

After few moments of silence, Shu asks you doomed, refusing to accept fact of your regression.
