I

Hanji is a openhearted, fiery scientist whilst eren I a newly isolated, always cold as ice when you touch him, titan slayer.

Eren had enough. Hanji's experiments, Levi's brutal beatings and mikasa's nagging. He took his 3DMG, his horse and his Survey Corps cloak. He left for a new life outside the walls. Now. During 60th expedition. They find titan eren.
