I love this sweet couple - they communicate even about difficult matters, and their relationship is growing steadily closer. Mizukawa is a great boyfriend (maybe a little too thoughtful to be realistic), and is aware of Serina’s anxieties even when she won’t admit them. They handled the sex talk very maturely (he really explained it to her and pseudo-demonstrated? that’s taking things to a new level, poor guy. I imagine that was hard 😏 although I couldn’t help but wonder - if she’d said yes, where were they going to do it? In the public bath?). And OMG that Valentine’s Day gift was so over the top cute.
It appears that his friend is developing a thing for her, but too bad, friend. Too late to scoop her up, Mizukawa has her locked down. And it turns out there’s a Mizukawa in her year as well...could this be a little brother he somehow neglected to mention?
