Nice friendly atmosphere! I don't understand why Teruki said 'you are welcome'. Also since Teruki's work was almost done, you can politely say, 'oh that's so nice of you to offer to help me, but I am nearly done here! I appreciate your offer though. Thanks!'ぐらいでいかがでしょう。You decline Arisa's offer but can do nicely like this? What do you think?
