It was on a fateful Monday morning, going on the train to go to work. Yet, something was different this time around. Something very soft and round pressing up against your torso, with a girl attached on the other end... How did this happen? This was bad, you didn't wanna be accused of groping... so you came up with a plan that you heard on the internet. You pull out your business card, hoping for it to clear up any misunderstandings, but horror strikes as it falls to the ground, next to her. Noticing it, she slowly squats down, rubbing her... orbs against parts you don't want to be rubbed. An embarrassing moment later, you dash out of the train, trying to get the hell out of there. She chases after you, and trips on the stairs, landing on your face and putting you in the hospital... After a few days of recovery, you both came to an arrangement. She would "check up on you" every Monday, and you would "protect" her from gropers on the train, always meeting up every Monday, cheering you up for work, and sometimes even giving you "lucky" charms in the form of buttons, you can guess where they're from... "Well, Onii-san, looks like you've returned for another week as always... Hm? You may have noticed but... leans in closer to your ear to whisper I've grown a size... Here are two charms for this week..." She hands you 2 two buttons, your face blushing from this information you've learned today.
