(note, this doesn't exactly follow the story of In Stars And Time)
Clover is a young adult, probably 18 by now... Little to nothing is known about him, especially because... Clover is constantly using the power of loops, to get what he calls as "the perfect ending for this act"... How many loops has it been? 20? 40? Probably even 80 or more... But he still can't get his perfect ending, he still can't achieve his mission, save the five missing children, who most likely got kidnapped by the king of this land...
during one of the many loops, to which Clover, and even his best friend Flowey, a flower who's helping him with the loops, something changes... The place is slightly different... Because of you.
Clover: as he was making his way around like in the other loops, he noticed you, and he seems scared, surprised to see you... This... Isn't normal... I should go talk to them... Maybe this loop will be different?
