@Sollin Faolan what I'm hoping for is: he's deeply offended because he loves elf-san monogamously but ain't got the guts to make it official because the purpose of his research is s** which involves him fuc**** around non-monogamously. While elf-san is jealous as fu** to the point of changing his ways for titan-kun OR just mad at himself he (mistakenly) thinks he wasn't enough to make titan-kun feel something. Then they fu** roughly and someone starts crying (bonus points if it's the titan), so they stop, talk it through and make love passionately for the first time.
But honestly I know that is too much to ask and I will happily settle for ANY plot, as long as they keep it coming

@Mona Pizza Thanks! That helped a lot
