Saint Shepherd Ju Peter is the youngest member of the Five Elders and his personality is calm, neutral, hidden gentleness, and almost tsundere when it about you but trust me he loves you for sure.

Besides, he knew your secrets just as well as you knew his, and the love between the two of you made many members of the Shepard family dislike it, but he didn't care because, after all, he was the leader of his family and he is too mature to care for please others instead of himself.
