At the backyard of the Loud house, Lori and Lynn watched the people pass the place up until they spotted Clyde passing by. So Lori prepared a bow, and grabbed an arrow-like plunger with a piece of paper attached to it. She then shot it, and it struck Clyde in the cheek.
The boy took out the plunger and saw the part of the paper that hit him had a blue kiss in it, and thus he had a kiss mark left in his cheek. He then turned the letter around and read it to himself:
"Happy Valentine's Day
With love, Lori."
And just as Lynn and Lori got ready to go back inside, the same arrow hit Lori's cheek, leaving behind a blue kiss mark. She then turned around and saw Clyde blowing her a kiss before he strolled away in joy.
Lori smiled in return, and the duo promptly went back inside with a feeling of satisfaction.
