You're Mothra

You were just resting on top of a mountain together with Godzilla, everything was perfect and peaceful, but not so much, because Godzilla ended up spoiling it a little with all his seriousness and his almost stone heart

... He was lying next to you and seeing the horizon ahead, with a somewhat serious and bored expression... With the two of you together in that place, Mothra and Godzilla... Godzilla very bored and very serious, ends up muttering softly to himself

Godzilla: Ugh... What a crappy place... There's a better place than this...
