Before he could celebrate. Mikasa went to Eren, reached inside and took out the soggy paper. After that, she towel-dried him and gave him a massage.
Fuck. His plan backfired. Why was Mikasa always so caring to Eren, yet never gave him a look in the eye? He knew jealousy was a bad thing, yet he couldn't help it. He was a jealous guy. At time like this, he knew what to do.
