Embarrassing each other at the bar

The day of the homework was coming closer. At school, Kei, Alex, Daisuke and Tanaka decided to organize the date for the next meeting. In the end, they went to a bar near their school that Saturday. "So, what do we do about the book?" asked Kei, who didn't have the smallest intention to use the absurd proposals of the other time. "Wait a moment" said Alex. His first priority was to eat something and he was calling the waiter. Then he said "We are in a bar, so we have to eat". Daisuke narrowed his eyes and was ready to answer 'We have to work', when he felt something on his arm. Tanaka was hugging it. So, before Daisuke could speak, he had already become pale. 'Oh, come on?!' he then thought, obviously annoyed. Then the waiter arrived. It was a girl. She looked at Daisuke and Tanaka and said, winking, "Do you two want a parfait?". Then again, Daisuke thought 'Oh, come on?!!'. And Alex started laughing deeply again. Now Daisuke looked at Kei with fawn-like eyes. He was his last resource. He had to hurry up and end the order before their reputation collapsed. "Ah, no thanks, my friend has a weak arm and she is helping him with the pain, because at PE he hitted it. He has a sore throat too today so he'd better not talk""Ah, then he should take something hot, is a tea ok?". Now Daisuke was looking at Kei with lion-like eyes, with a totally different expression than before. His face was saying 'Where did you take that excuse from?'. Then he thought 'Wait, she believed him?! But I want an ice cream!'. Instead, Kei shook his shoulders as if to say 'You'll have to settle for that'. Meanwhile, Alex was still laughing. The reason why Daisuke wanted to protect their reputation was because that was a bar mostly frequented by students of their school. Alex's reputation was since long gone, but there were still him and Kei. He didn't care about Tanaka. But now, he will be remembered by some as the weak who needs help, or worse, somebody might bully him. That was no problem, because when he was a child he did a bit of karate, but that was still a nuisance. Nobody wants to be a target. In the end, he drank the tea. If he would have talked, he would have uncovered the lie. Luckily people didn't eavesdrop, but Alex's laughter caught a bit of attention, and Daisuke and Tanaka were wrongly labeled as lovebirds. Just so you know, the misunderstanding won't be cleared soon. The order ended smoothly (more or less) and, after they finished eating, they decided to focus on the book. They wanted to decide the plot, then the best one at writing would have written it, another one would have taken care of putting everything in order and so on.
