My Little, Stray Cat

Mirei always uses her cat as an excuse to avoid drinking after work with her co-workers. However, the "cat" she is referring to is her younger boyfriend, Ryou, who moved into her place right after he graduated high school. She isn't sure if he's still going to University. What does he do all day? There are many questions she would like to ask him. One evening, Mirei comes home to find Ryou has left, without a word. Like a real cat, all of a sudden he is gone. But where did he go and will he come back to her? And why does she see him starring on a popular television show?
