I sat across from one of the suspects, Sara. She is claimed to be the victim's girlfriend.

" Okay so Sara-ssi, I have a question." IU said. " When you asked Kiyeob-ssi to pick you up, did he by any chance go into the house while you were somewhere else?" IU asked.

Sara crossed her arms. " Yeah, but only for about 2 minutes. Look, I know Kiyeob, he didn't do it." 

IU felt strange by her words. " Look, I am only doing my job." IU said, then continued to ask questions.

" Did Kiyeob tell you something when he got back?" IU asked. " He said that he heard Taesung talking to Minwoo." Sara replied.

" Okay, this might be personal, but in the first interview, you said that you and Taesung had a little argurment, agree?" IU asked again. Sara nodded.

" What was it about?" 

" It wasn't something related to this case." Sara turned her head away.

" Still, this little argurement can help us figure out who killed Taesung." IU said.

" He told me that he saw me the other night with MinWoo at a club." Sara confessed.

IU wrote every single word down.

" Why were you there with MinWoo?" 

" MinWoo said that he just wanted to hang out, like old times." IU lifted her eyebrows.

" Like old times?" IU asked.

" Yeah, back in high school, it was just MinWoo and I. Taesung was the new student. When Taesung and I went out, I forgot all about Min....Woo." Sara trembled. 

" So all of this puts all the suspection on MinWoo." IU said.

" You think he did it?" Sara asked.

" This is just a thought or suggestion." IU explained.

" But your facts did help, actually a lot." IU thanked. 

" And, the night of Taesung's death, you went straight home, am I correct?" IU said.

" Yeah." Sara simply said.

" Do you know where Minwoo was that night?" IU asked.

" No, well he was with Taesung, or that's what I thought." 

" Okay, thank you for your hard work. We hope that you're innocent, Sara-ssi." IU bowed, and left the interviewing room.

Over all facts:

• Minwoo and Sara had a realtionship before Taesung came. 
• After Taesung came, Minwoo might hae wanted revenage after being forgotten by Sara.
• It seems like Kiyeob had nothing to do with it.
• Sara had said that Taesung spotted Sara with Minwoo.
• Sara went straight home after Kiyeob dropped her off.
