An age gap romance between a 30 something lady and a 23 year old guy? Sign me up! Misuzu looks so sad, because the only person who gave her purpose in life never really cared about her. Masato, I hope you get what you deserve soon.
Misuzu felt so hollow, the wedding of her best friend couldn't cheer her up. Isshiki wants to help fill the void in her heart, and I bet it's because he's been in love with her since he was a child! He's already done so much by making her cake much better!
I find it funny that even Misuzu couldn't understand the meaning of calling Isshiki a dog.
