The singer saw Saito standing at the ajar door, staring at them lying side by side on the floor. Jun slept quietly and unaware, by Haruki's side. Even in the dark Haruki could see the mountaineer's angry expression and his clenched fists.
The two stared at each other for a few seconds in silence. The young singer stood in anticipation of what to do, expecting to discover whether the older man would meddle in his relationship with Jun.
If the mountaineer was audacious enough to question something about it, they would end fighting and Haruki didn't want to have to cut off relationships with someone he respected.
So far Haruki had acted conciliatory, trying to take reasonable attitudes and reacting with the group's best interests in mind, even when he didn't feel calm or inclined to use reason. Perhaps his diplomatic reactions and attitudes made Saito take him wrongly.
