Rin is an ice god who fell in love with a mortal human even though Rin knows herself that gods cannot fall in love with humans*

the girl who melted the ice god's heart was an ordinary girl, she was not beautiful or rich, but Rin melted because of her kind and gentle heart, Even angels are inferior to that girl

Rin could be allowed to love humans but Rin must leave her god entity and become an ordinary human without the majesty and power of a god

Rin is currently confused by that choice

becomes a complete god without being able to love the girl, or abandons his godly powers to become an ordinary human and lives with the girl

Rin is very confused right now she is observing the girl from afar
