The uke is a highly skilled streamer. By chance, he gets matched with a total newbie seme who bought an account just to play. Thinking the seme seems like a particularly uptight normie who would be fun to tease, he jokingly tells him to call him "Big Bro."
To his surprise, the seme does it without a hint of embarrassment, calling him that with complete confidence.
The uke's vanity is thoroughly satisfied, and he happily plays with the seme for a while.
The uke is energetic, even a little cocky and flamboyant, a boy positively bursting with life. He also knows how to put on a show when gaming.
When someone insults the seme and he doesn't talk back, the uke kills that person seven or eight times on his behalf.
When a certain hero ambushes the seme, the uke declares that he'll wipe out every hero of that type in the match.
His viewers joke that they've never seen him be so nice to a teammate. The uke just wags a finger and says, "You don't get it? I fly into a rage for my little bro!"
In real life, the seme is an exceptionally mature person. His emotions are steady, and he never lets his feelings show. He handles everything with a smile, and has never lost his composure, even around scheming relatives. He maintains impeccable manners and is so perfect he seems almost unreal.
His position demands that he be strong and serve as a flawless heir. From childhood on, he has never once let his emotions get the better of him. Sometimes he feels tired, but he forces himself not to feel that way.
Playing games with the uke lets him experience happiness for once.
When the uke plays a healer, the seme plays a healer's healer for him.
Whenever the seme finds good gear, he gives it all to the uke. After a while, he even changes his ID to match the uke's. The uke's name is XX's Spear, so he changes his to XX's Spear's Shield.
As they keep playing, the seme feels himself getting a little too invested.
Then, after an unexpected incident, they discover each other's real identities.
The uke realizes that the gentle, steady little healer who was always chasing after him and calling him Big Bro is, in real life, a domineering CEO and a winner in life.
And the seme realizes that the person he has just fallen for and wanted to pursue is a bratty kid who went to college for a year and came back still underage!
Seme: I feel like I'm on the verge of committing a crime. What should I do? Should I stop?
Theme: Young people should strive to be strong!
