The girl was trying to learn from the other dude. She realizes MC's advice was spot on, thinks back, realizes all his advice was good advice, then feels awful about it and hopes to apologize next stream.
However, by this point, the MC's creepy classmate (an otherwise attractive girl) has joined the dungeon and is training under him. She became a dungeon explorer because she's in love with him and realized she needs to lessen his burden if he's gonna have time to date her (since his rejection when she confessed was, "I'm sorry but I don't have enough time to date anyone.")
