"hi i'm the girl that reads your texts, and i'm in love with you" 

Minatozaki Sana and Myoui Mina both know someone is stalking their texts at work (over the work wifi(everyone in the news room knows, It's company policy)) but they cant bring themselves to take it seriously. Ignoring these policies, they end up conversing about their private life that should probably not be read by others. 

Chou Tzuyu, The one who was hired to monitor other people's work wifi usage was expecting her job as a "Internet Security Officer ISO" to be more of a internet hacker and crushing firewalls - not writing a report everytime someone uses the internet inapropriately.

When Tzuyu comes across the ladies' messages, she knows she has to report them but she can't help but be captivated by their hilarious messages. 

When she ends up falling for one of them, she realizes she knows too much about them to introduce herself.

what would she even say...?
