Shuichi nodded in response, but before he could lead Kokichi anywhere, in the corner of his eye, he spotted another phantom thief, this time one with green hair. Before he could do anything or really process the other thief's presence, he noticed that he was running up to them. It seemed likely that he worked with Kokichi.
"What happened here?" he asked softly as he saw Kokichi. "Is this the detective you're in love with?"
Shuichi blushed a bit at the comment. "I-in…in love with…?" he questioned before shaking his head. "N-never mind… T-to explain…th-this…um, well…h-he almost…fell… I-I…um, I managed…to save him…"
Due to being embarrassed by the comment and his general social anxiety, he ended up stuttering a fair bit while he was speaking, and his face remained red. However, Rantaro didn't seem to mind this. All the detective did notice was that he seemed concerned, but that made sense since he just explained that Kokichi had almost fallen off the building to his death.
"Ah, so that's what happened, huh?" he asked, his tone surprisingly calm. He looked at Kokichi before looking at Shuichi. "Both of you should head home. Just lead the way to your place. I'll carry him. Seriously, Detective, I can tell that you're exhausted, and my partner is likely traumatized. It's best if you both leave."
Shuichi didn't argue with that as he handed Kokichi over to Rantaro. Once the other picked him up, he began to lead the two back to his house. Luckily no other detectives had been around, so if asked, Shuichi could just say that Kokichi got away. He never had to mention Rantaro's presence since he didn't seem to be known about. Maybe things would be alright after they got home.
