27 seconds.

That was how long it took Childe to break up with you over the phone. He muttered a "sorry" before hanging up – an insincere apology so he didn't look like the bad guy. He didn't tell you why nor did he have to see you cry yourself to sleep that night.

You heard he had got his arm around a new lover. He was busy picking up her while you were picking up your heart. You never got past the breakup, but it didn't seem to phase him in the slightest.

He was Mr. Perfectly Fine.
