That’s a hard comparison because we know light years more about Evgeni than outcome. But I think I’d pick Evgeni. I wouldn’t have to give up my entire life for him, like I would need to for Outcome. But good ask!
When I'm sad I think about the Heiwajima parents meeting Izaya and Ruri and being so happy that their sons found someone who gets them. I also think about how if Shizuo and Izaya would be the brother-in-law to Kasuka and how the twins would pounce on that fact. I just like to think about fluffy family dynamics T-T
THE FAMILY DINNERS WOULD BE SO CHAOTIC.
Ruri would feel so out of place despite being probably the only person who can pretend that she is actually normal, and Izaya would tell her so and unintentionally make her feel better.
Mairu and Kururi would obviously invite themselves to every family gathering which of course Izaya and Shizuo would both say no and they’d show up anyway.
Shizuo’s parents would just be happy for the generally amicable atmosphere though I feel!
