I (Yamaguchi Tadashi) have noticed that my best friend (Tsukishima Kei) has been acting strange lately. Tsukki- no Kei, has been acting much nicer than ever before by giving me compliments and doing things for me. For once he interested in my love life and then he wants me to call him by his first name? I have noticed that other people have been acting different as well. That gets me thinking... What is it with Kei? Status: Main Story Complete
