How does the present tense work in a relative clause?

Question

> そんなわけで、まだ日も暮れない夕方の通学路を、駅に向かってゆっくりと歩く俺と加藤。 I encountered this quote in a light novel and am stuck on how to interpret it. It feels like 歩く should be "walking" in this context, but it is not 歩いている. The sentence does not seem to express future or habitual action like the dictionary form of a verb usually does either.

Answer 1

Not knowing where this came from and therefore lacking context, but the action may not have taken place yet:

そんなわけで、まだ日も暮れない夕方の通学路を、駅に向かってゆっくりと歩く俺と加藤 - For that reason, it was I who would walk slowly toward the station along the road to school on an evening when the sun had not yet set, with Kato.
