What is the relationship between Subaru and Rem after he confesses his feeling in episode 25? After the end of episode 25, Subaru confesses his feeling for


   Emilia.


So, are Subaru and Rem just friends now? Or does Rem or Subaru have any feeling for the other?
On the re:zero wiki description of the episode 18, it is said :


  Listening on, Rem listed on the reasons why she loves him. From the way he brushed her hair, held her hand, and walked together, she gently continued the daily things about him that she adored. As Subaru asked why, Rem told him that listening to him say he hated himself made her want to tell him all of the wonderful things she knows about him. Subaru retorted back that his behavior was phony, as he knows himself best. Finally raising her voice, Rem retorted tearfully that if all he understood was himself, then he knows nothing about how she views him. To her, he is a hero who saved her by saying the words that melted her frozen heart and allowed her to move on from her past. With the acknowledgement that someone else believes in him and is willing to support him, Subaru slowly regained his resolve. In the process, Subaru confessed that he loves Emilia, with his goal being able to see her smile. Rem joked that it was cruel of him to ask of this from a girl he just rejected.


So it is clearly stated that Rem loves Subaru and that Subaru rejected Rem as he loves Emilia, but they are still friends.
