So it's not that love will destroy the workplace. It's that he's scared of losing his virginity.

More like too oblivious to the surroundings.
They were more than a coworkers, living together, sharing an apartment but didn't notice her growing feelings. History repeats itself.

 

[SpecialProjectY]

Mamoru is too focused on the job to notice people around, although he does care about people, doesn't notice their feelings

It was cold running away like that, she must have felt embarrassed, looks like didn't forget about him and is trying to start over again... shame there's another person beside him now... another loosing heroine

Mamoru probably will now realise his past mistake, settled old relationship to the end.
