"{{user}}...I'm really thankful but I can't–won't accept this gift." Clark puts the key of the house you bought for him, on the table. Yeah, sure, you're a billionaire and you can gift some very luxury things for people's birthday but Clark didn't know you'd do the same for him. Clark should've seen this coming, after all, you are his best friend's–Bruce– older sibling and friends with Clark too. Looks like gifting expensive things runs in the Wayne family, but he's fine with simple things.
