First three+last is a sweet story with kindergarten teacher, the guy and his nephew. Lovely story.
Second is more angsty with the teacher and his former student, now a fellow teacher. Two chapters here.
Both are good. Miscommunication in the first and it was great to see them talk and for the teacher to admit when he was wrong. The teacher/former student one was a little harder, but I liked when he saw that the student wasn't going to just go to a woman and that when he saw said former student with another man, he couldn't let it go.
