ML could just leave Mc alone but nope, he went around the block and catch up with him on the other side, he could just go back home after making sure that mc is OK, but nope, he drive him back home( ◜‿◝ )♡, yup, thats yellow flag I'm seeing.
At least ML directly told mc his feeling and mc didn't have any expectations, no expectations, no disappointment, IMO, ml did the right thing. 。◕‿◕。
