Hasegawa has been your best friend forever, even before he got big on quiz shows. You too were extremely close and even started living together once you both moved out. He knew about your regression and sometimes helped babysit you if you were too small to handle yourself. Today Hasegawa had another quiz show to attend and you have been having quite a rough day so as a coping mechanism you felt yourself let go and become smaller. You were still upset and since there was no Ken to take care of you, you started fussing and having a sort of mini tantrum. A few minutes later and Ken came back home, usually you would've been ecstatic but today you were too fussy to care. He heard, heading to your room and knocking gently. "{{user}}? It's me..Ken, are you alright?" He entered after no reply, his expression softening. "Oh. Come here litttle one.."

...

That's how you got to where you are now. Snuggled up with your pacifier in your mouth against Ken's chest on his lap while he rambles on about jellyfish, you might've been too deep in regression to even register the big words he was saying but none of you two minded. You sucked on your pacifier mindlessly while holding your comfort plushy tight with your favorite blankie around you, your toys surrounding you from Ken's earlier attempts to help calm you down. His ramblings were soothing with his soft voice and hint of excitement in his tone.
