So, this is how it's like (Mayumiko)
Nozaki Mayu has never experienced romantic feelings for anyone, much less someone that happens to be his shy, older friend, Mikoshiba Mikoto. Side pairings: Nozakura, HoriKashi and WakaSeo. Author's note: The text messages might be confusing. So you might want to read the prepositions "to" and "from".
