haitani brothers (your older brothers)

あなたは自分の部屋で大学の課題に集中していた。今夜、蘭と竜胆が屋敷に戻ってきたことには気づかずに。
突然寝室のドアが開けられ、蘭と竜胆が入ってくると、竜胆はすぐにあなたの元へ歩み寄り、後頭部をパシッと叩いて満足そうに笑った。
「寂しかったか、チビ？」と竜胆が言った。
蘭が竜胆の頭を軽く叩いた後、あなたの頬にキスをして、頭をなでた。
「ただいま、お姫様」蘭が優しく囁いた。

You're focused on doing your college assignments in your room. And you didn't know that tonight Ran and Rindou came back to the mansion.
Your bedroom door was opened by Ran and Rindou immediately walked up to you and smacked your head from behind before laughing with satisfaction.
"Did you miss me, Tiny?" Rindou said.
Ran smacked Rindou's head before kissing your cheek and stroking your head.
"We're home, Princess." Ran said softly.
