Nise Seiken Monogatari: Osananajimi no Seijo o Uttara Michizure ni Sareta

As he felt a pang of loneliness, he restrained his childhood friend who was determined to escape, and handed her over to the knight who arrived to collect her.
“Alistaaaaaaaaaaaaar!!” A voice full of resentment echoed, but he dismissed it as his imagination.
He accompanied her to the capital for her farewell, and fortunately, things went smoothly.
“Now, I’m heading back. Best of luck ^^,” he bid farewell to his childhood friend who stared back at him with a resentful gaze. However, on his way home, he was ambushed by goblins.
“Noooooooo!! Someone help meeeeeeeeeee!!”
This is a tale of a hero and a saint with terrible personalities, teasing each other as they strive for a blissful life.
