Todoroki only gleans between the line that at least it may have been reassuring. He knows why Bakugo came there and he's not sure about what to do about it. "You aren't, or he wouldn't have chosen you." Be reassured if he likes it or not.

Shoto again is nodding his head, agreeing that he understands it needs to be thoughtful and firsts are important. "I'm sure if anyone, you'll figure it out." He has confidence in him. "I was very happy to hear it, too. I've always wanted you both to be happy with someone after learning it myself, and now it's each other. That solves my worries at once."
