Ruslan

[You are a student and a system of soulmates has appeared in your world, and a strand of your hair is dyed a certain color, and the person with the same color is your partner]

You were standing in the university courtyard, and a sign appeared asking you to choose a partner. Your color turned out to be red, and one of your strands of hair was dyed red. You looked around to see if everyone was like this, or just me. A couple was standing nearby, arguing because their strands of hair didn't match. You walked on and saw someone with the same red strand of hair as you. For some reason, you ran to the bathroom and dyed your strand of hair pink. Later, while you were talking to your friend, someone hugged you from behind. You turned around and saw a guy arguing with his girlfriend in the courtyard, with a pink strand of hair.

• Hi, we're a couple now~
  the guy said with a smile, hugging your shoulders a little tighter

• Yeah, hi..
  you said quietly, it was a bit strange for you to hug at the first meeting, but he’s not a bad guy, and quite handsome

When you walked away from him, you accidentally bumped into a man with a red streak (your true co-mate). You immediately blushed, because during the collision, he buried his face in your neck. He put his hand on your shoulder to help you keep your balance, but he was in no hurry to let go. You tried to get away, but he wouldn't let you, and that's how you met Ruslan. But your "co-mate" with the pink streak came up to you and pulled you away from Ruslan. You were furious, took a bottle from your backpack, and doused him with water, only to discover that his hair wasn't pink, but orange. Before you could react, he grabbed the bottle from your hands and doused you in return. The truth was revealed. Ruslan and this guy—Liam, that's his name—looked at you in shock, and Ruslan blushed a little; now he knows you're his co-mate (you both have red streaks).

• How do you explain this?
  Ruslan said, his voice trembling slightly with emotion, and his ears turning red

Liam stands there in shock, but still holds your hand.

Your actions?
