Maybe they’re opposites physically speaking (and “physically” I mean that one is thin and the other is a little chubby, and just that, because for me both are really cute and beautiful and- DID YOU EVER SEEN CHOUJI USING THAT CALORIE CONTROL SHIT??? HE LOOKS HELLA HOT) but their personalities are quite the same imo. Like:

Both are kind

Like really really kind

(People usually thinks that Ino is not kind bUT SHE IS GODDAMMIT!!!)

Both really care for their friends and teammates

Both are loyal friends

The only thing that I would really consider of opposite on them (cuz I will not consider a physical thing) is the fact that Ino’s really confident and Chouji is not (he has no self esteem), but idk, seeing how he is acting in the Fourth Shinobi World War, it seems like Chouji has overcome this issue, so yeah, I don’t really think they’re opposites at all. 

For me, Shikamaru and Ino are clearly opposites. ♥

Because:

Ino is a sassy gorgeous troublesome girl, and Shikamaru is a lazy average guy

Ino is bossy, and Shikamaru just takes orders when given

Shikamaru always uses his brain to resolve everything (he is the rationality of the relashionship), and Ino uses her heart (she is the emotion of the relashionship).

She is, basically, the exact opposite of the kind of girl he had wanted to marry (and how Shikamaru is an ironic character, and usually nothing goes according to his plans, we can assume that there’s a good chance of these two end up together)

And what is even cooler about ShikaIno is the fact that, even they being opposites, they have a lot in common too, like:

BOTH ARE REALLY GOOD FRIENDS, LIKE, THE BEST FRIENDS SOMEONE COULD EVER ASK FOR (BECAUSE THEY’RE SUPER PROTECTIVE AND CARING AND THEY WOULD DIE FOR THEIR FRIENDS LIKE WOW THEY’RE THE BEST FRIENDS OF THE ENTIRE WORLD)

Both helped a beloved friend to gain confidence (Shikamaru: Chouji; Ino: Sakura)

BOTH HATE BULLIES 

Both are SUPER INTELLIGENT

EVEN WITH THEIR DIFFERENCES, THEY HAVE THIS AMAZING BOND LIKE WOW THEY CLEARLY LOVE EACH OTHER (even people that don’t ship them know that, because InoShikaChou love each other very much)

(Ok, I better stop here because I’m getting a little too excited talking about them)
