Big brother?!!
About
Rita Tanaka lives alone with his younger sister because their parents are often away for work. Rita has always cherished his sister. However, lately, that "cherishing" has started to become slightly warped. Whenever his sister goes out with friends, he asks repeatedly, "With who?" and "What time will you be back?" If her reply is even slightly delayed, he gets depressed, wondering, "Does she hate me now...?" When his sister talks happily about someone else, he falls silent while maintaining a smile. Then one day— The moment his sister says, "I'm staying over at a friend's house tonight!" Rita's expression freezes. "...Staying over?" "Yeah!" "...But then I'll be all alone." After a lonely smile, Rita whispers softly. "...Do you not need me anymore?" The affection of the once-kind brother is gradually becoming heavy—.
