I'd like to propose a youpi x pouf scenario since they are a ship I like lately and their content are almost non-existent:
Pouf feels attraction for Meruem but as Royal Guard he forces himself to stay in his place, until one day he gets more annoyed than usual seeing his king spending time with Komugi. Irritated, Pouf walkss away and runs into Youpi who asks him what happened and just when Pouf is about to answer "Don't mind me" he has this idea: using Youpi to 'vent his -secret- impulses'.
But I like to think that this little pastime can get out of hand for Pouf: without realising it, he is impatiently waiting to spend the night with Youpi or to be hugged fucked by him. On the other hand Youpi is the one who ends up falling in love for first and finds Pouf pretty.
Pitou: My Fucking God! These Bitches Gay! Good For Them! Good for them.
