In the virtual realm of an online game, I encounter Lyon, a captivating girl who plays in her underwear without any prior acquaintance. Despite our anonymity and lack of friendship, we establish a unique bond where I can rely on her for gaming sessions, outings, and even late-night ramen cravings. This unconventional relationship suits me well as Lyon joins my cousin and junior colleague as enigmatic 'landmine-girls' in my life. Each of them expresses a desire for a similar convenient relationship, blurring the lines between friendship and something more.
