I'm Done Being a Hero, Even If It's Retirement

“A hero must be heroic until the very end.” Adelia, a knight who devoted her entire life to the empire and ended her life as a hero. But when I opened my eyes... '9 years old? I?!' I was back in my childhood! Back to the time when everyone was alive before the family fell! Yes, this is a God-given opportunity. This time, I will save everyone and enjoy a perfect retirement in a quiet place! But... ''Sister...!'' It wasn't enough to wake up the holy sword that had been sleeping in the temple for 600 years, "Does the princess... have a taste for tall people?" "...yes?" The crown prince who was my boss in a past life is showing interest in me? Why are you doing this? I want to retire quietly! [source MLT using google translate] Original Webtoon: ,
