He was chill when he confessed to Kyouya because Kyouya almost kissed him the previous day when drunk. It's shown that the next day when Kyouya wakes up, Motoharu is sitting by the side with panda eyes like he didn't sleep all night and was thinking things through. Since he now knows that Kyouya likes him, he has no reason to hold back.
Y'all a final decision + 4 years of suffering + overthinking is too heavy for a stupid misunderstanding. Wtf? He was chill when he confessed to Kyouya, kinda implying that he knows that Kyouya won't say no and that Kyouya has feelings for him. He wasn't in the least bit surprised when Kyouya started crying wtf
