We have a winner for #2 (thx helix), now the question is if we can get the 1st
No problem ^^ I'm just reading it, so cute! But I really want to know the 1st one, it sounds familiar, but I can't find it

1.) Highschooler walks in on two guys kissing, they see him, and then they kinda force him to join them. They reveal they're the school's secret detective team and they want him to join and after they go around fixing people's love problems. 2.) Guy gets laid off, fails to get a job, etc., and asks his brother to help him out, brother lets him stay in company dorms and he is called the floor pet (a cat), he ends up dating the one guy he didn't like and gets a separate house with him.
