In the light novel Volume 5, In the cram school, Saki asked Hachiman accompany her to a nearby restaurant to give advice to her brother and she doeesn't take no for an answer.Hachiman followed her, after learning that Komachi is with him. There Hachiman adviced Taishi about the requirements to Sobu High school, its benefits and other high school as well. After both of their sisters went to get something to eat, Taishi  asked about his interest in girls at Sobu High in comparison to Yukino and Yui. Understanding his mindset and also the reason why Taihi wanted to talk to him from the beginning, Hachiman gives a full fledged explanation of Class 2f.

Difference in Light novel and Anime adaptation

In Volume 9  he also participated along with Saki in discussion to help Hachiman to stop Yukino and Yui from running for the president of student council, even though Hachiman didn't want his help..Hachiman annoyingly refered Taishi as that thing.Komachi explained that Hachiman may need help or opinion of someone in the same class as he is and decided to ask Saki through Taishi.(Since Komachi didn't have Saki's contacts)

However Taishi's presence is completely removed in anime adaption in Episode 5 of Season 2. Where Saki alone accompanied Saika and Komachi to give idea.
