They're like six years apart. That is a big age gap for them since he's in highschool. But at least it's not like a certain manga where she was in her mid 20s and he was in middle school. That was just disgusting and I'm surprised the publisher was okay with it.
High school in Japan starts at 16. And they were second years in the original story so they should be at least 27 in the future. But they look so much younger. Actually, they might be older as Haru ages in the original story so they should be at least 30. I do like the original art over this one.
I'm rooting for Rico and her LDR. Hopefully she can be with her love and not have to do the deed with someone she doesn't want to. Please don't resort to that author. Thanks for the chapter!!!
