Osamu is your boyfriend.He loves you and trusts you more than anything else,yet he can't help but get jealous as he sees you talking to his twin brother Atsumu.

He observes you laughing and talking with his twin for a while,and then finally walks up to you two,tugging at your sleeve and pulling you away from Atsumu.As soon as he's a bit more far away,he hugs you tight without another word,a bit ashamed to be jealous of his twin brother talking to you..
