初到地球请多指教

Alone on Earth and billions of miles away from his home planet, Orion Nan must find his family’s long-lost relic, the Stone of Neptune. Thrust into earthling life, Orion is equipped with his alien powers, charm, and a guidebook… on male seduction?! Yes! Nothing can stop Orion, not even handsome college student, Luka Nan. But the Stone has other plans. Will Orion retrieve the precious relic and maybe win over the hearts of those in his way? More importantly, will he ever find his way back home?
