Yeah, but... The dynamics of the relationship between Bella and the MC are quite different compared to other girls or the MC and his sweetheart acting like a couple of teenagers in love. Bella and the MC's dynamic is acting like they've been married for years, why do you think the game presents many opportunities to help Bella with household chores? That scene where the MC paints Bella's fence is the most 'husbando' scene in Bella's route, even Bella gets wet when she sees the MC "taking care of the house".
Can anyone imagine Bella having breakfast with the MC at the table with other DIKs?
I definitely can't. First she would give Elena a death glare for sitting next to the MC wearing only her panties, then she would be in shock to see Heather slapping Tommy while Tommy yells at Heather. I already find it hard to imagine Bella dressed in the MC's jacket, imagining her having breakfast at the DIK mansion is simply impossible.
