Is there any ambiguous language and action between the male and female lead of the anime "Ice Fruit"?

" Ice Fruit " was a light novel and anime set in modern Japan. It told the story of four students with different personalities who met in the library on a cold winter night. They became good friends after a misunderstanding and solved all kinds of problems together. In the whole story, the interactions between the male protagonist, Zhizhige, and the female protagonist, Kanda Airu, were quite frequent. There were some ambiguous words and actions. For example, Zhezhi had once confessed to Chifan, but he had used some suggestive words such as " I've been thinking about you " and " My feelings for you are getting deeper and deeper." These words and actions indicated that his feelings for Chifan had gone beyond the scope of friendship. In addition, there were some other ambiguous plots in the story, such as when Zouji and Chibanta were taking a walk in the snowy night, Chibanta gently put his hand on Zouji's waist, or when they were reading together in the library, their eyes met, etc. These plots all showed the subtle relationship between them. Although there were some ambiguous words and actions, the main characters in Ice Fruit paid great attention to friendship and respect, so these plots would not cause too many misunderstandings and troubles.
