So I see three possible scenarios : 1. Intern-chan is taking Sempai aside to tell him that Douki-chan is after and that he should make a move already 2. Intern-chan is a mastermind that pitted Douki-chan and Rival-chan against each other to keep Sempai all for herself 3. The "Onii-an" is litteral and Intern-chan is actually Sempai' sister

After researching her behaviors (i.e. little personal space, looks foreign, affectionate to those she just met) I have come to the conclusion that she is from Argentina. There is a large Japanese population there as well.
