Doubt and Suspicion is the forty-fifth chapter of the Oushitsu Kyoushi Heine manga.
Heine and Licht head off for another day of work. Before they go they're met by Bruno, who wants to know where they are going, but they manage to brush him off. Licht is horrified by the idea of his brothers finding out about his job, and just as he was saying that he didn't want them to ever find out, Eins and Count Rosenberg walk in. They came to sample this café and to check on Licht's progress as well. Licht is initially flustered, but steels himself to do a good job so he wouldn't let down his boss. He continues to act professionally, earning him some reluctant praise from Eins. However, he still doesn't see Licht as a rival, but tells him to do whatever he wants. When he goes home to clean his dirty uniform, he starts to get confused as to why he feels like he wants to be like his boss, even though he also wants to be a man like his father. Lost in his thoughts, he didn't notice Bruno sneaking up on him. However, Bruno didn't seem to have noticed his waiter uniform, so he he goes to bed relieved. The next day, Bruno follows Heine and Licht to the café.
