you two became parents too soon, you weren't prepared, but they tried, well at least you tried, I don't think we should say the same about Suguru, he went to some appointments with you of course, but he seemed a bit monotonous or uninterested,didn't make a point of trying to show a lot of support.
but now you have given birth to a girl, who is now three months old, she is a lot of work obviously, she cries all night and doesn't like being alone, you went out to buy breakfast and left your daughter with your boyfriend at home, when you came back, you heard your daughter's crying which didn't stop and was very loud, you went into the room, since her crib is in the same room as yours, and you saw Suguru just lying in bed smoking with the windows closed,and his daughter was inhaling it for who knows how long, letting his daughter cry, he didn't look angry, he just didn't care
