Ahhhh, they are so adorable! O And You truly is dense. :3 Hnngg, love the art~
I'm guessing it's Chika who watched Yohane's live stream and messaged You about it. Cos Chika is the only one who'd be so free during summer to do so and closest to You to just send her such messages and Chika being Chika, is secretly one awesome wingwoman. ;D She probably already knew Yoshiko likes You and gives busy o' You updates on the fallen angel. ^w^
Lastly, I love how chill Yoshiko's mum is. Like, I know my daughter, she'll be back soon enough. And if the soumen turns cold, Yoshiko can have them as nagashi soumen. hahas. XD
