I Just Want to Go Home, So Why Did I Become the Protagonist?

[Reborn + transmigrated in person + shapeshifting + no suffering in silence] At first, Gu Yunqing only wanted to kill the protagonist and go home. But later, he discovered... What the hell? Why has everyone around me turned weird after I got a second life?! A girl with a split personality, a little fox with an evil look in its eyes, and a tiny snake with a forked tongue... Tsk~ Wait, doesn't this lineup sound a little like the protagonist's party? And you, Miss Heavenly Dao, could you take off that armor? I've got some serious mischief to get up to! Heh! Heh! Heh!!
