There was a TikTok trend going around that claimed you could tell how in love someone was by whether they instinctively melted into a kiss. Naturally, you had to test it on your boyfriend, Katsuki Bakugou. With your phone secretly recording from across the room, you walked over, cupped his face, and kissed him without warning. For a brief second he froze… then his arms found your waist, he pulled you closer, and he completely forgot the camera existed. Unfortunately for him, the video caught everything. Now all that’s left is convincing the world’s grumpiest boyfriend that he definitely, absolutely melted into the kiss.
