Another reason why Lin Yi joined this case was that his good roommate, that unlucky man, Zhang Zhiyuan, was identified by the police as the suspect who killed Li Yudie.
What happened is this: Zhang Zhiyuan and Li Yudie did not know each other because of the campus love letter incident.
He was originally shy, but he didn't expect that this time he would actually get to know Li Yudie and even add her on WeChat.
He has always regarded Li Yudie as a goddess in his heart, and he no longer has to look up to the aloof Li Yudie.
Because he could already talk to her, sometimes Li Yudie would invite him to watch her games.
However, Li Yudie asked Zhang Zhiyuan to call Lin Yi together every time, and most of the topics they talked about after meeting were around Lin Yi alone.
This made Zhang Zhiyuan somewhat depressed. He knew very well that Lin Yi was indeed much better than him.
Girls generally like tall, handsome, and smart boys like Lin Yi.
Zhang Zhiyuan himself pales in comparison to Lin Yi.
But Zhang Zhiyuan feels that it is a big progress for him to be close to Li Yudie now.
Besides, Lin Yi had told him in front of him that he focused on his studies now and would not fall in love with any random girl on campus.
Zhang Zhiyuan believed in Lin Yi's character, and he knew that Lin Yi would be able to do what he said. It was obvious that Lin Yi was really not interested in Li Yudie. Zhang Zhiyuan felt that as long as he had perseverance, he would be able to make it happen one day.
Li Yudie shifted her thoughts from Lin Yi to herself.
As long as you have perseverance, even stubborn stones will be moved.
But the person Li Yudie liked in her heart was not Zhang Zhiyuan. She was originally thinking of dating Lin Yi, but Zhang Zhiyuan did not bring Lin Yi over by the way.
After just a few times, Li Yudie lost her patience. She stopped dating Zhang Zhiyuan, and it seemed that Zhang Zhiyuan's use value was gone.
Lin Yi was neither salty nor cool towards her, and had no intention of dating her.
Zhang Zhiyuan used to have a good attitude, but suddenly he gave up.
On the morning of Li Yudie's death, Zhang Zhiyuan and Li Yudie had a quarrel again in the school cafeteria.
"Why are you doing this to me? Are you just playing with me for so long?"
After Zhang Zhiyuan made several appointments with Li Yudie, but Li Yudie didn't agree, he finally broke out.
Li Yudie said to Zhang Zhiyuan: "I have no other intentions for you, I just treat you as an ordinary friend. You asked me to invite you to dinner, and of course I refused you if I didn't want to go."
Zhang Zhiyuan was particularly angry.
"You just think of me as a tool, but actually your target is Lin Yi, right?"
Li Yudie did not deny it. Zhang Zhiyuan did not need to say this, it was just the same thing.
Zhang Zhiyuan didn't need to press any more. More and more people gathered in the canteen. After all, it was in this canteen that they caused such a big farce last time.
He slammed the chair hard and walked away.
This incident was reported to the police by the roommate who went to have breakfast with Li Yudie. At that time, everyone saw that Zhang Zhiyuan was so angry that his neck turned red.
Li Yudie looked indifferent and finished her breakfast calmly.
Therefore, before Li Yudie died, the only person who had a conflict with her was Zhang Zhiyuan.
Therefore, Zhang Zhiyuan naturally became the subject of police suspicion and was called for questioning.
