Between Sakusa and Atsumu, it is obvious that the blonde setter is more extroverted and loud.
That's perhaps a fact. Between them, Atsumu is more vocal, proud, and showy while Kiyoomi Sakusa's just as timid as he usually is. Even when they started going out together. It is very seldom for Sakusa to show affection towards his now boyfriend, Atsumu Miya.
Atsumu, however, wasn't demanding for all of that especially when they were in public. That's Sakusa Kiyoomi we are talking about, so the blonde doesn't even ask beyond what the spiker could give.
Atsumu receives attention from the spiker whenever the latter wants to practice serves or new playing technique. That was enough.
Atsumu's the one who loves giving suprises during their monthsary and anniversaries, and Kiyoomi would just smile receiving those bouquets and gifts.
If you are thinking that Kiyoomi's a boring boyfriend, well, you're definitely wrong, gravely mistaken!
Between the two, Kiyoomi Sakusa was more clingy than Atsumu! Kiyoomi always wants cuddle during their day off from practice, and even when they are having get away games. He would always want physical contact with his setter. He would intertwine their fingers together, put his hands on Atsumu's waist when the blonde is busy cooking, he would lay his head on Atsumu's lap and even insist of taking shower together!
About surprises... Kiyoomi would actually book vacation getaways and give Atsumu the best and luxurious gifts. Atsumu's spoiled with all these things, only provided that it's between the two of them.
Kiyoomi doesn't like the idea of posting anything he had done, but Atsumu always keeps insisting. The setter would post, but only their pictures together at Bali or at Seoul, but not the actual gift he received. He respects Kiyoomi's decision despite their differences. It's just a matter of understanding after all.
While Kiyoomi Sakusa could really keep his poker face outside, in closed doors, he's such a baby who would always require Atsumu's attention.
In front of Osamu, Sakusa would maintain that professional stature, and make mature choices, but once alone again with Atsumu, he would apologize for not buying Atsumu chocolate ice cream because Osamu said it's not healthy.
"I don't think spoiling Tsumu would make him mature, Kiyoomi-san." Osamu defended
"I... agree. Okay..." the spiker said looking at the pout Atsumu made.
"Great! We really get along so well, Kiyoomi- san!" and Osamu proudly announced that.
Kiyoomi smiled and held Atsumu's hand tightly. Approval and acceptance is what Kiyoomi always wanted especially with his relationship with Atsumu.
He wanted to keep his relationship private, yet he always wished to shout to the entire world how lucky he is dating Atsumu Miya.
He would watch Atsumu sleeps at night, and smiles to himself, as he wrapped his arms around his boyfriend.
Kiyoomi Sakusa and Atsumu Miya has two different personalities, but we can all agree that both of them are clingy in their own simple yet romantic way.
