it has hit me that Yakov is a single father with 4 adoptive children that include:
eldest son, pride of the family, set the standard and now everyone else is fucked (except in the memory department cause everyone is better than him there), ran away with his Japanese boyfriend and their dog, family kinda coming around for the guy cause he is cool though.
second son, always compared to the first, more in tune with feelings than the eldest one but so much so that he becomes total mess when sad, takes breakups badly, likely a sad drunk, still happy that the big bro has a cool boyfriend though
the only girl, is closest with her younger bro, stronger than any of the boys and they are proud of her, takes breakups better than second bro, wants to know your personal life, props bi, looks more fashionable than you is regular work out clothes
youngest child, mom’s favorite as well as grandpa’s favorite, is angry all the time (unless grandpa is there), knows their new brother in-law the best and hates admitting he likes the guy, only seems to love cats (maybe too much), gains motivation out of spite, wants to surpass his eldest bro and is on his way to do so, talented af but boy can that arrogance be a bitch
surprise son in-law that Yakov was like, the last person to know about, warming up to the guy though, only person capable of dealing with eldest son’s bs, probs makes good Katsudon for everyone, too pure for them to hate him at the end of the day, same name as youngest son, not very good with Russian but he tries
