Escape Journey
I really like the fact this shows them going on as a couple and the hardships they face, but the relationship gets stronger. It doesn't end with "they got together and everything was happy ever after." You get to care about the characters more.

1. Sex friend introduces his twin brother. It moves to a 3p, then the twin falls in love. 2. Friends who started dating and living together. One is unemployed and obsessed with the other (and has a slight pee fetish) so when he starts going out and working on his computer all the time, his lover gets worried. 3. Man rejects his best friend after a graduation confession. Years later they meet again as coworkers. 4. Playboy catches otaku taking pictures of a popular girl and blackmails him into being his slave.
