I'm late at checking for new chapter because of various reasons. And now it's already been 3 weeks... Shame on myself!
Awkward, but lol @ Hato's response. I can see that he's trying to be calm. His answer to sempai guy's question was kind of deep and sad, but sempai guy trying to make "it" work. The sempai who was drunk and sleeping besides them woke up suddenly and broke the mood (in another meaning). Both of them regretted about it and blamed on being drunk later, though.
Back to graduation trip next.
