My Guardian Is an Incubus

From Rose Squad Scans:
My guardian is an incubus?! Because he didn't wish to receive his sinnaerim (T/N: his personal gods for practicing Shamanism) a high school boy attempted to call a greater God but summoned a demon instead. Among the demons, he summoned a demon of lust, an incubus and this is the pure(?) story of the guardianship of the high schooler by the demon.
