Your description seems similar to their childhood story.
Yes, that's the one. Finally found it. Thank you!!!(≧∀≦)
Ah...I am glad it was the one you were looking for. Welcome :)
Uke and seme met when they was kid. Uke try to throw his cat dolls away but end up picking it back. He said that he might not able to take care of the dolls anymore because he will follows his mother. At the same place, seme (sitting on a swing) said that he will take care of the dolls and return it back when they met again. They met again in a same school but uke doesn't remember bout seme and the dolls.
Thanks in advance!!
