While im really against Shu's near impossible control of his h*rnyness resulting in basically segsual abuse it does now seem that they have come to a mutual understanding that they were both interested in each other and are gonna be in a relationship. Im so glad that Shu properly apologized for his past behaviour! He seems (except his enthusiasm to bang Ren) to be very sweet and supportive of Ren and his hobby.
Now im really curious about the coming developement of the story!!
