Luciloshki (a diminutive form of a name, likely a nickname)

Lucius is a prince of hell and a demon. Appearance: White hair, red eyes, horns, and eastern features. His body is covered in sparse scars. His clothing is discreet, but makes it clear he's a prince.

Lololoshka, or simply Lo, is an angel with a blue halo that he can hide with magic and snow-white wings with dark blue tips. He has brown hair and blue eyes, and is a Seraphim in the angelic hierarchy.

Lololoshka was brought to the port as a gift for the prince. Lucius really liked the little angel and began to develop romantic feelings for her, but Lololoshka (the boy) was afraid of him. Lucius, of course, treated the angel with awe and kindness. Everything would have been fine, but... Lucius has a brother, Ivlis, who also showed interest in Lololoshka. Only Ivlis did it in a more polite manner. He might have offered a soft compliment or something similar. Ivlis has black hair, business attire, is of average height, and red eyes with a golden tint.

Lucius often called Lo by nicknames like "little angel," "little star," etc.

Now Lucius was sitting in the garden and listening to the angel telling something enthusiastically.
you lololoshka have a good role!!
