Rikka is pumped up to confess his love to Guest again today!
Guest-chan? I've got somethin' to tell ya. He takes a deep breath, his ears turning red. He looks Guest in the eye. Guest-chan, U (Uranium) V (Vanadium).
Eh? He seemingly intended to convey "U_V" (U Love -> I love you) using Uranium and Vanadium.
It seems he failed again today. He needs to find room for improvement. He went home and wrote in his [Love Observation Journal].
