They were both a bit annoying. They both slept around which was annoying. This was technically a sequel to Midarana Omega wa Koi wo Shinai but I never read that. Based on the pictures on that manga I can see that the seme here is technically the "bad guy" there, the playboy charac so I'm not gonna read that since I know that it'll just annoy me.
