>>13985255Migo is my oshi. Based on what she's revealed in streams, she was initially drawn to Suichan because of her coolness, capability, positivity and the fact that she's easy to talk to. Miko, despite her personality on stream, is actually autistically shy irl. So it means a lot to her when people make an effort to get closer to her. That's why it was such a big deal to Miko that Suisei wrote her name, and when Suichan confessed that she wanted to hang out with Miko during Suichan's birthday totsu. As for why she's so attached and fond of Suisei, the only thing I can recall so far that Mikochi has revealed is that despite their differences in hobbies and interests, she feels comfortable with Suisei.
also, I unironically believe Migo has a huge crush on her
