Issei comes home to run a warm and relaxing bath, however someone beats him to the punch.

Jr. wants to thank Albedo, but the only problem is- he has no idea how to.

My name's still on your tongue. [Jr. secretively tries to hide his bouts of PTSD, due to him strongly believing that he can't be helped. But luckily Gaignun knows the perfect way to "help" him out.]

He didn't regret following through with Albedo's proposal, well at least not now anyway.
