Let’s Compare
First, let’s consider the idea of “imagining a situation different from reality and feeling regret or disappointment about it.”
[Examples]
料理がもっと上手ならばよかった。
I wish I were better at cooking.
料理がもっと上手ならばよかったのに。
I wish I were better at cooking.
Both sentences share the assumption that “in reality, the speaker is not good at cooking, but they are imagining if they were.”
“ばよかった” simply expresses the wish that “it would have been good if I were better at cooking.”
On the other hand, “ばよかったのに” conveys a stronger sense of disappointment regarding the fact that they are not good at cooking.
Additionally, since the speaker’s feelings are often omitted after “のに,” it can imply a result-based regret, such as:
（料理がもっと上手ならばよかったのに）みんなにまずい料理を出してしまった。
(I wish I were better at cooking, but) I ended up serving bad food to everyone.
Next, let’s examine the difference in the speaker’s feelings from the perspective of “regret or reflection on past actions.”
[Examples]
車で来たけど、道が渋滞しているから電車に乗ればよかったね。
I came by car, but the roads are congested. We should have taken the train.
⇒ This expresses simple regret or disappointment about a past action, reflecting on the idea that “I should have chosen a different option.”
あのときバスではなく電車に乗ればよかったのに、バスに乗ってしまいました。
I should have taken the train instead of the bus back then, but I ended up taking the bus.
⇒ This emphasizes regret over not choosing a better option in a past situation.
The phrase “ばよかったのに” highlights the fact that the speaker had a better alternative but did not choose it.
The omitted part after “のに” often implies the actual action taken (riding the bus) and the speaker’s disappointment with the outcome.
Finally, let’s focus on “ばよかったのに.”
“ばよかったのに” is used when the speaker expresses disappointment or criticism toward the listener’s past actions. In many cases, what follows “のに” is omitted.
[Examples]
A「今朝、授業に間に合わなかったんだ。」
B「もっと早く起きればよかったのに。」
A: I didn’t make it to class on time this morning.
B: You should have gotten up earlier.
⇒ The phrase after “のに” is omitted, but it implies “However, you didn’t wake up early,” carrying a sense of criticism from the speaker.
A「昨日は何も予定がなくて本当に暇だったよ。」
B「え、私に連絡してくれればよかったのに。」
A: I had nothing planned yesterday and was really bored.
B: What? You should have contacted me.
⇒ The omitted part after “のに” implies “However, you didn’t contact me,” expressing the speaker’s disappointment.
