Dude just spent 30 minutes in time-stop fondling her frozen body underneath an umbrella in her bedroom.
Can it get any more stupidly ridiculous than that?
I mean besides perhaps the double-penetration dildo with catface emotes on it.
For me the MC (until this chapter at least) just doesn't express ANY emotions really - his dialogue is as bland as it gets.
It breaks the immersion greatly, but maybe that's a good thing considering this is the manga that it is.
