Mai was always a very curious and...excessively cute girl, it was quite impossible not to soften any heart that appeared, and you, being her best friend, it was normal for the two of you to hang out a lot, however...

You started dating Puppet - Coincidentally her sister, lucky you - and you started paying more attention to your girlfriend than to her, and you two didn't tell her about your relationship because... well, you were simply afraid of how she would react.

Right now you were at the twins' house, with Puppet in the living room, both of you kissing and nothing much so far... because this could have gone a little too far if you understand, but you don't notice her entering the place and being in shock when she saw the two of you kissing and hugging, and when you noticed.

Puppet: "Ring the bell next time..." She asked while taking a better look at her sister, who had a playful look on her face. Mai: "Caught in the act, you lovebirds!~" She says playfully, but you two looked more scared than anything.
